Question 1.

A group of 7 friends has 15 dollars to share What is each person’s share?

Answer:

Number of dollars each person shares = 2.14.

Number of friends = 7.

Number of dollars they have = 15.

Number of dollars each person shares = Number of dollars they have ÷ Number of friends

= 15 ÷ 7

= 2.14

Question 2.

Gail rode her bicycle 325 miles in 5 days. How many miles did she ride each day?

Answer:

Number of miles she rides each day = 65.

Explanation:

Number of miles Gail rode her bicycle = 325.

Number of days = 5.

Number of miles she rides each day = Number of miles Gail rode her bicycle ÷ Number of days

= 325 ÷ 5

= 65.

Question 3.

A diesel engine uses 100 quarts of oil for cooling. If the engine has 6 cylinders, how many quarts are there per cylinder?

Answer:

Number of quarts are there per cylinder = 16.67.

Explanation:

Number of quarts of oil for cooling a diesel engine uses = 100.

Number of cylinders the engine has = 6.

Number of quarts are there per cylinder = Number of quarts of oil for cooling a diesel engine uses ÷ Number of cylinders the engine has

= 100 ÷ 6

= 16.67.

Question 4.

Jack used 6 pounds of butter in a recipe for 30 loaves of bread. How much butter did he use for each loaf of bread?

Answer:

Number of pounds of butter he uses for each loaf of bread = 5.

Explanation:

Number of pounds of butter in a recipe Jack used = 6.

Number of loaves of bread Jack uses = 30.

Number of pounds of butter he uses for each loaf of bread = Number of loaves of bread Jack uses ÷ Number of pounds of butter in a recipe Jack used

= 30 ÷ 6

= 5.

Question 5.

It took 75 tons of gravel to cover 3 miles of road. How much gravel was used for each mile?

Answer:

Number of tons of gravel used for each mile = 25.

Explanation:

Number of tons of gravel used = 75.

Number of miles of road = 3.

Number of tons of gravel used for each mile = Number of tons of gravel used ÷ Number of miles of road

= 75 ÷ 3

= 25.

Question 6.

At a restaurant, 6 people want to share 3 pizzas. if there are 8 slices in every pizza, how many slices does each person get?

Answer:

Number of slices each person gets = 4.

Explanation:

Number of people = 6.

Number of pizzas to share = 3.

Number of slices in every pizza = 8.

Total number of slices of pizzas = Number of pizzas to share × Number of slices in every pizza

= 3 × 8

= 24.

Number of slices each person gets = Total number of slices of pizzas ÷ Number of people

= 24 ÷ 6

= 4.

Question 7.

If a house has 2,000 square feet of wall surface to be painted and Marcia has already painted 1,600 square feet, what portion of the wall still needs to be painted?

Answer:

Number of square feet of portion of the wall still needs to be painted = 400.

Explanation:

Number of square feet of wall surface to be painted in a house = 2,000.

Number of square feet of Marcia has already painted = 1,600.

Number of square feet of portion of the wall still needs to be painted = Number of square feet of wall surface to be painted in a house – Number of square feet of Marcia has already painted

= 2,000 – 1,600

= 400.

Question 8.

Tom put 8 gallons of gasoline into a 23-gallon tank. How much of the tank did he fill?

= 23 – 8

= 15.
