Like and Unlike Decimals

Are you confused about how to check if Decimal Numbers are Like or Unlike? If so, you have arrived at the right place as you will get a complete idea of the entire concept of Like and Unlike Decimals. Get to Know in detail the Like and Unlike Decimals such as Definitions, Procedure to Convert Unlike Decimals to Like Decimals, Solved Examples, etc. in the later sections.

Like and Unlike Decimals – Definitions

Decimals having the same number of decimal places i.e. decimals having the same number of digits on the right side of the decimal part are called Like Decimals.

Example: 2.35, 6.54, 7.28 are all Like Decimals

On the other hand, Decimals having a different number of decimals i.e. decimals having different digits on the right side of the decimal part are called, Unlike Decimals.

Example: 4.56, 7.854, 9.634 are Unlike Decimals

How to Check if given Decimal Numbers are Like and Unlike?

Like Decimals will have the same number of digits after the decimal point. For Example, 2.34 and 5.76 are like decimals since both the numbers have 2 decimal places after the decimal point.

Unlike Decimals will not have the same number of decimal places after the decimal point. For Example, 3.2 and 4.568 are unlike since both of them don’t have the same number of decimal places after the decimal point.

How to Convert Unlike Decimals to Like Decimals?

If we place any number of annexing zeros on the right side of the extreme right digit of the decimal part of a number then the value of the number is not altered. Thus, Unlike Decimals can be converted to Like Decimals by annexing with the required number of zeros on the extreme right digit in the decimal part.

We can convert Unlike Decimals to Like Decimals by simply adding Zeros to the right of the Decimal Point or by finding the Equivalent Decimal. However, Unlike Decimals can also be equivalent decimals. For Example, 0.4, 0.40, 0.400 are all, Unlike Decimals but not equivalent decimals.

Like and Unlike Decimals Examples

1. Check if the two decimals are like or unlike: 43.47 and 53.895?

Solution:

Given Decimals are 43.47 and 53.895

Number of Decimal Places in 43.47 = 2

Number of Decimal Places in 53.895 = 3

Since both the numbers don’t have the same number of decimal places in the decimal part given decimals are unlike decimals.

2. Check if two decimals 34.5 and 547.6 are like or unlike?

Solution:

Given Decimals are 34.5 and 547.6

Number of Decimal Places in 34.5 = 1

Number of Decimal Places in 547.6 = 1

Since both the numbers have the same number of decimal places in the decimal part given decimals are like decimals

3. Convert Decimals 1.3, 4.23, 6.756 into Like Decimals?

Solution:

Given Decimals are 1.3, 4.23, 6.756

To Change the given Unlike Decimals to Like Decimals annex with a required number of zeros as placing the zeros after the right side of the decimal part will not alter the value.

Decimal Places in 1.3 = 1

Decimal Places in 4.23 = 2

Decimal Places in 6.756 = 3

To make them into like decimals annex with the required number of Zeros

Annexing with Zeros for the given decimals to make them like decimals

1.3 ➝1.300

4.23➝4.230

6.756➝6.756

Thus, given decimals changed to like decimals are 1.300, 4.230, 6.756

Straight Line in Two-Point Form – Formula, Examples | How to find the Equation of a Straight Line Passing through Two Points

Straight Line in Two-Point Form

The equation of a straight line represents each and every point on that line. Let us consider the straight line created by passing through the two points such as (a1, b1) and (a2, b2). There are no curves present in the straight line. The basic equation for the straight line in Two-point for is ax + by + c = 0. Here, a, b, c are constants, and x and y are variables.

How to find the Equation of a Straight Line Passing Through Two Points?

The below diagram shows the straight line in two-point form. In this, (a1, b1) is the starting point of the straight line, and (a2, b2) is the ending point of the straight line.

Straight line in Two-point form. Image 1

The equation of the straight line which is passing through the two points A(a1, b1) and B(a2, b2) is b – b1 = (b2 – b1) / (a2 – a1) * (a – a1). P(a, b)is the joining point of A and B.
The straight line is passing through the two points A and B. Then the slope of the line AB = (b1 – b2) / (a1- a2).———( 1 ).
Now, the straight line is passing through the two – points A and P. Then the slope of the line AP = (b – b1) / (a – a1). ——- ( 2 ).
To find out the equation of a straight line with two point form, we need to equate the two equations. That is,
Slope of the line AP = Slope of the line AB.
(b – b1) / (a – a1) = (b1 – b2) / (a1 – a2).
(b – b1) = (b1 – b2) / (a1 – a2) * (a – a1).
Equation for the straight line of two – point form is equal to (b – b1) = (b1 – b2) / (a1 – a2) * (a – a1).
Let us consider the slope (b1 – b2) / (a1 – a2) as ‘m’. substitute the value in the above equation. Then straight line equation becomes as
(b – b1) = m(a – a1).

Steps to Solve Equation of the Straight Line Problems

Follow the three steps to find the Equation of the Straight Line. They are

1. Find the slope of the line.
2. Put the slope and one point into the “Point-Slope Formula”.
3. Simplify the equation.

Two – Point Form Examples with Solutions

1. Find the Equation of the straight line passing through the points (1, 2), and (3, -2)?

Solution:
The given details are (a1, b1) = (1, 2) and (a2, b2) = (3, -2).
The equation for the straight line is (b – b1) = (b1 – b2) / (a1 – a2) * (a – a1).
Substitute the values in the above equation, then we will get
(b – 2) = (2 – (-2)) / (1 – 3) * (a – 1).
(b – 2) = (2 + 2) / (-2) * (a – 1).
(b – 2) = 4 / (-2) * (a – 1).
(b – 2) = -2 * ( a – 1).
b – 2 = -2a + 1.
2a + b – 2 -1 = 0.
2a + b – 3 = 0.

Finally the straight line equation is 2a + b – 3 = 0.

2. Find the equation of the straight line joining the points (-2, 4) and (5, 6)?

Solution:
As per the given information, the straight line is created by joining the two – points. They are (a1, b1) = (-2, 4) and (a2, b2) = (5, 6).
Equation for the straight line of joining two points is (b – b1) = (b1 – b2) / (a1 – a2) * (a – a1).
Substitute the values in the above equation, then we will get like
(b – 4) = (4 – 6) / (-2 – 5) * (a – (-2)).
(b – 4) = (- 2 / – 7) *(a + 2).
(b –4) (7) = 2 * (a + 2).
7b – 28 = 2a + 4.
-2a + 7b – 28 – 4 = 0.
-2a + 7b -32 = 0.

Therefore, the final equation for the straight line is -2a +7b – 32 = 0.

3. Find the straight-line equation with the help of two points (6, 2) and (8, 4)?

Solution:
The given information is the straight line is crossing the two points. They are (a1, b1) = (6, 2) and (a2, b2) = (8, 4).
The equation for the straight line in Two – point form is (b – b1) = (b1 – b2) / (a1 – a2) * (a – a1).
Substitute the values in the above equation, we will get
(b – 2) = (2 – 4) / ( 6 – 8) * ( a – 6).
(b – 2) = ( – 2) / ( – 2) * (a – 6).
(b – 2) = (a – 6).
-a + b – 2 + 6 = 0.
-a + b + 4 = 0.
a – b – 4 = 0.

Finally, the equation for the straight line in two – points is equal to a – b – 4 = 0.

4. Find the equation of a straight line that is passing through points A(6, 6) and B(10, 4)?

Solution:
As per the given information, the straight line is passing through the two points. They are
(a1, b1) = (6, 6) and (a2, b2) = (10, 4).
The basic equation for the straight line in two – point form is (b – b1) = (b1 – b2) / (a1 – a2) * (a – a1).
Substitute the above values in the equation. Then we will get like
(b – 6) = (6 – 4) / (6 – 10) * (a – 6).
(b – 6) = 2 / (-4) * (a – 6).
(b – 6) = 1 / (-2) * (a – 6).
-2 ( b – 6) = a – 6.
-2b + 12 = a – 6.
-a – 2b + 12 + 6 = 0.
a + 2b – 18 = 0.

Finally the equation for the straight line is a + 2b – 18 = 0.

5. Find the values of a for which the points A(a, -2), B(4, 2) and C(8, 10) are collinear?

Solution:
As per the given information, the given points A(a, -2), B(4, 2), and C(8, 10) are collinear.
(a, b) = (a, -2), (a1, b1) = (4, 2), and (a2, b2) = (8, 10)
So, the slope of the AB = slope of the BC.
(b1 – b) / (a1 – a) = (b2 – b1) / (a2 – a1).
Substitute the values in the above equation. Then we will get
(2 – (-2)) / ( 4 – a) = (10 – 2) / (8 – 4).
(2 + 2) / (4 – a) = 8 / 4.
4 / (4 – a) = 2.
4 = 2(4 – a).
4 – a = 2.
4 – 2 = a.
a = 2.

Finally, a is equal to 2.
