Question 27.
6 pizzas were shared equally among a group of children. Each child got \(\frac{1}{9}\) of a pizza. How many children were in the group?
Answer:
The number of children were in the group is 54 children.

Explanation:
Given that 6 pizzas were shared equally among a group of children and each child got \(\frac{1}{9}\) of a pizza. So the number of children were in the group is 6 ÷ \(\frac{1}{9}\)
= 6 × 9
= 54 children.

Question 28.
A rectangle has an area of 15 square meters. It ¡s divided into parts, each with an area of \(\frac{3}{8}\) square meter. Into how many parts has the rectangle been divided?
Answer:
The number of parts has the rectangle been divided is 40 square meters.

Explanation:
Given that a rectangle has an area of 15 square meters and it ¡s divided into parts, each with an area of \(\frac{3}{8}\) square meter. So the number of parts has the rectangle been divided is 15 ÷ \(\frac{3}{8}\)
= 15 × \(\frac{8}{3}\)
= 5 × 8
= 40 square meters.

Answer:
The number of tacos can Maria make is 15 tacos.

Explanation:
Given that Maria buys 8\(\frac{1}{3}\) pounds of beef to make tacos for a party which is \(\frac{25}{3}\) and she uses \(\frac{5}{9}\) pound of beef for each taco. So the number of tacos can Maria make is \(\frac{25}{3}\) ÷ \(\frac{5}{9}\)
= \(\frac{25}{3}\) × \(\frac{9}{5}\)
= 5 × 3
= 15.

The capacity of a large milk carton is 1\(\frac{1}{2}\) liters. A dozen large cartons are poured into a container and then poured into small cartons that each hold \(\frac{3}{10}\) liter. How many small cartons of milk can be filled?
Answer:
The number of small cartons of milk that can be filled is 60 cartons.

Explanation:
Given that the capacity of a large milk carton is 1\(\frac{1}{2}\) liters which is \(\frac{3}{2}\), so in pounds, it will be 12 × \(\frac{3}{2}\)
= 6 × 3
= 18.
And a dozen large cartons are poured into a container and then poured into small cartons that each hold \(\frac{3}{10}\) liter. Here, the total number of small cartons of milk can be filled = Total number of pounds of a dozen large cartons ÷ small carton capacity which is
= 18 ÷ \(\frac{3}{10}\)
= 18 × \(\frac{10}{3}\)
= 6 × 10
= 60.
The number of small cartons of milk that can be filled is 60 cartons.
