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:

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.
