Question 1.
A group of 7 friends has 15 dollars to share What is each person’s share?
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?
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?
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?
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?
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?
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?
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.
