Question 1.
Circle the number that is less than the number of cubes.

The number that is less than the number of cubes = 3.

Explanation:
In the above-given figure,
given that,
there are 5 cubes.
the given numbers in the question are 3, 5, and 8.
3 is less than 5.
3 < 5.
8 is greater than 5.
8 > 5.
so the number we have to circle = 3.

Question 2.
Circle the number that is greater than the number of cubes.

The number that is greater than the number of cubes = 5.

Explanation:
In the above-given figure,
given that,
there are 3 cubes.
the given numbers in the question are 1, 3, and 5.
1 is less than 3.
1 < 3.
5 is greater than 3.
5 > 3.
so the number we have to circle = 5.

Question 3.
Circle the symbol that is used to compare two numbers
+      –         >

The symbol that is used to compare two numbers = greater than.

Explanation:
In the above-given question,
given that,
the three symbols are +, -, and >.
+ symbol is used to add two numbers.
example : 2 + 3 = 5.
– symbol is used to subtract two numbers.
example : 5 – 1 = 4.
> symbol is used to compare two numbers.
example : 3 > 1.

Comparing Numbers
Question 4.
Choose two numbers to make the sentence true.
_________ is less than ________.
