Question 1.

After each soccer practice, Scott runs 4 sprints of 20 yards each. If he continues his routine, how many practices will it take for Scott to have sprinted a total of 2 miles combined?

Scott sprints _____ yards each practice. Since there are _____ yards in 2 miles, he will need to continue his routine for _____ practices.

Type below:

__________

Answer:

Multiply 20 yard × 4 = 80 yards

Now convert from yards to miles

1 mile = 1760 yard

x = 1760 × 2 = 3520 yards

p = 3520 yards/80 yard = 44

Thus he will need to do 44 practices.

Question 2.

A worker at a mill is loading 5-lb bags of flour into boxes to deliver to a local warehouse. Each box holds 12 bags of flour. If the warehouse orders 3 Tons of flour, how many boxes are needed to fulfill the order?

_____ bags

Answer: 100 bags

Explanation:

A worker at a mill is loading 5-lb bags of flour into boxes to deliver to a local warehouse.

Each box holds 12 bags of flour.

Pounds of flour per box

x = 12 × 5 lb = 60 lb

We need to multiply by the conversion rule

1 T = 2000 lb

Find out how many pounds are in 3 tons. Pounds of flour in the warehouse.

y = 3 T × 2000 lb = 6,000 lb

Divide by the number of pounds per box. 100 boxes are needed.

b = 6000/60 = 100 boxes.

Question 3.

Cory brings five 1-gallon jugs of juice to serve during parent night at his school. If the paper cups he is using for drinks can hold 8 fluid ounces, how many drinks can Cory serve for parent night?

_____ drinks

Answer: 80 drinks

Explanation:

First, convert from gallons to quarts

We are converting larger unit to the smaller unit.

1 gal = 4 qt

We need to multiply by the conversion rule.

x = 5 gal × 4 qt

x = 20 qt

Next, convert from quarts to pints.

2 pt = 1 qt

We need to multiply by the conversion rule.

y = 20 qt × 2 pt = 40 pt

Next, convert from pints to cups.

We are converting from a larger unit to a smaller unit.

1 pt = 2 cups

y = 40 pt × 2 c = 80 c

Now convert from cups to ounces

1 c = 8 oz

y = 80 c × 8 oz = 640 oz

d = 640 oz/ 8 oz = 80 drinks

Cory can serve 80 drinks for parent night.

Question 4.

A science teacher needs to collect lake water for a lab she is teaching. The lab requires each student to use 4 fluid ounces of lake water. If 68 students are participating, how many pints of lake water will the teacher need to collect?

_____ pints

Answer: 1 pint

Explanation:

Answer: 5 rotations

Explanation:

When Jamie’s car moves forward such that each tire makes one full rotation, the car has traveled 72 inches.

Convert from a smaller unit to the larger unit.

Convert from inches to yards.

36 in = 1 yard

x = 72 in/ 36 in = 2 yards

Find out how many rotations are needed.

y = 10 yard/ 2 yard = 5 yard

The tired need to make 5 rotations for Jame’s car to travel 10 yards.

Question 7.

A male African elephant weighs 7 Tons. If a male African lion at the local zoo weighs \(\frac{1}{40}\) of the weight of the male African elephant, how many pounds does the lion weigh?

Explanation:

Convert from Tons to pounds

1 T = 2,000 lb

Find out how many pounds are in 7 Tons.

y = 7 T × 2000 lb = 14,000 lb

The weight of the elephant is 14,000 lb

Find the weight of the lion

l = 14,000 × 1/40 = 350 lb

Therefore the weight of the lion is 350 pounds.

Question 8.

Explanation:

First, we need to find the total weight of the case of pencils

w = 64 boxes × 2.5 oz = 160 oz

Now convert from ounces to pounds

We are converting from a smaller unit to a larger unit.

1 lb = 16 oz

y = 160 oz/16 oz = 10 lb

Thus total is 10 pounds.

Question 11.

Test Prep For a class assignment, students are asked to record the total amount of water they drink in one day. Melinda records that she drank four 8-fluid ounce glasses of water and two 1-pint bottles. How many quarts of water did Melinda drink during the day?

Options:

a. 2 quarts

b. 4 quarts

c. 6 quarts

d. 8 quarts

Answer: 2 quarts

Explanation:

Given that,

Melinda records that she drank four 8-fluid ounce glasses of water and two 1-pint bottles

Question 15.

Kelly made one batch of peanut and pretzel snack mix. How many grams does she need to add to the snack mix to make 2 kilograms?

_____ g

Answer: 575 grams

Explanation:

Kelly made one batch of peanut and pretzel snack mix.

From the above figure, we can see that batch of peanut and pretzel snack mix is 1425 grams

To find how many grams she needs to add to the snack mix to make 2 kilograms

We have to subtract 1425 grams from 2 kgs

1 kg = 1000 grams

Total number of DVDs = 35 – 9 – 12 = 14 DVDs

Thus Marsha has 14 DVDs.

Question 6.

Kevin is making a picture frame. He has a piece of trim that is 4 feet long. How many 14-inch-long pieces can Kevin cut from the trim? How much of a foot will he have left over?

Type below:

__________

Answer: 1/2 ft

Explanation:

Kevin is making a picture frame. He has a piece of trim that is 4 feet long.

Converting from feet to inches

1 feet = 12 inches

x = 4 × 12 = 48 inches

Calculate how many 14 inch pieces. He can cut 3 (14 inch) pieces

y = 48 ÷ 14 = 3

48 – 42 = 6 inches

Feet leftover

6 in/12 in = 1/2 feet

Thus 1/2 foot will be left over.

Question 7.

_____ \(\frac{□}{□}\) cups

Answer: 4 \(\frac{1}{8}\) cups

Explanation:

Given:

Carla uses 2 \(\frac{3}{4}\) cups of flour and 1 \(\frac{3}{8}\) cups of sugar in her cookie recipe.

Add 2 \(\frac{3}{4}\) and 1 \(\frac{3}{8}\)

2 \(\frac{3}{4}\) + 1 \(\frac{3}{8}\)

2 + 1 + \(\frac{3}{4}\) + \(\frac{3}{8}\)

3 + \(\frac{3}{4}\) + \(\frac{3}{8}\)

3 + \(\frac{9}{8}\)

3 + 1\(\frac{1}{8}\)

3 + 1 + \(\frac{1}{8}\)

4 \(\frac{1}{8}\) cups

Question 9.

Tony needs 16-inch-long pieces of gold chain to make each of 3 necklaces. He has a piece of chain that is 4 \(\frac{1}{2}\) feet long. How much chain will he have left after making the necklaces?

Options:

a. 6 inches

b. 12 inches

c. 18 inches

d. 24 inches

Answer: 6 inches

Explanation:

Given that,

Tony needs 16-inch-long pieces of gold chain to make each of 3 necklaces.

He has a piece of chain that is 4 \(\frac{1}{2}\) feet long.

Converting from feet to inches.

1 foot = 12 inches

4 feet = 12 × 4 = 48 inches

1/2 feet = 6 inches

48 + 6 = 54 inches

Tony needs 16-inch-long pieces of gold chain to make each of 3 necklaces.

16 × 3 = 48

54 inches – 48 inches = 6 inches

Thus the correct answer is option A.

Question 15.

Which Internet services downloaded the podcast in less than 4 minutes?

_________

_________

Answer:

Groove Box

Internet -C

Explanation:

From the above figure, we can observe that the Internet services downloaded the podcast in less than 4 minutes is Groove Box and Internet -C

Groove box took 173 sec and Internet-C took 196 seconds.

Convert from minutes to seconds

1 min = 60 sec

1 sec= 1/60 min

173 sec = 2 min 53 sec

196 sec = 180 sec + 16 sec = 3 min 16 sec

Question 16.

Which service took the longest to download the podcast? How much longer did it take than Red Fox in minutes and seconds?

Type below:

_________

Answer: Top Hat

Explanation:

The figure shows that Top Hat took the longest time to download the podcast.

It took 1050 sec to download the podcast.

Convert from minutes to seconds

1 min = 60 sec

1 sec= 1/60 min

1050 sec = 1020 sec 30 sec

1020 sec = 1020 × 1/60 min = 17 min

1050 sec = 17 min 30 sec.

To find how much time it took than Red Fox, we need to subtract the time from red fox and top hat.

1050 sec – 310 sec = 740 sec

Convert from seconds to minutes.

1 min = 60 sec

1 sec = 1/60 min

740 sec = 720 + 20 sec

720 sec = 720 × 1/60 = 12 min

740 sec = 12 min 20 sec

Question 17.

Which service was faster, Red Fox or Internet-C? How much faster in minutes and seconds?

Type below:

_________

Answer: Internet-C

Explanation:

From the above figure, we can see that Internet-C is faster than Red Fox.

Internet-C took 196 sec

Red Fox took 310 sec

310 sec – 196 sec = 114 sec

Convert from seconds to minutes.

1 min = 60 sec

1 sec = 1/60 min

114 sec = 60 sec + 54 sec

114 sec = 1 min 54 sec

Question 18.

Explain how you could find the number of seconds in a full 24-hour day. Then solve.

Now convert from minutes to seconds.

1 min = 60 sec

1440 min = 1440 × 60 = 86400 sec

Thus a day has 86400 seconds.
