Lesson 20 - Interpreting Remainders

Front

What is a remainder in division?

Back

A remainder is the amount left over after division when one number cannot be divided evenly by another.

Front

How do you calculate the number of trips needed if you have a total number of people and a bus capacity?

Back

Divide the total number of people by the bus capacity. If there is a remainder, you need an additional trip.

Front

If 160 people need to be transported and a bus holds 30 people, how many trips are needed?

Back

6 trips (because 160 ÷ 30 = 5 remainder 10, so 5 full trips and 1 additional trip for the remaining 10 people).

Front

What is the process to split a quantity equally between two groups?

Back

Divide the total quantity by the number of groups.

Front

If Harish has 3 cups of brown sugar for 2 loaves of banana bread, how much sugar does each loaf get?

Back

Each loaf gets 1.5 cups of brown sugar (3 ÷ 2 = 1.5).

Front

How many cakes can Tina make if each cake requires 2 eggs and she has 9 eggs?

Back

Tina can make 4 cakes (because 9 ÷ 2 = 4 remainder 1, so she can make 4 full cakes with 1 egg left over).

Front

What is the formula to find out how many items can be made with a limited resource?

Back

Divide the total amount of the resource by the amount needed for one item.

Front

If Jessica has 8 cups of blueberries and wants to divide them among 3 pies, how many cups does each pie get?

Back

Each pie gets 2 and 2/3 cups of blueberries (8 ÷ 3 = 2 remainder 2, which is 2 and 2/3).

Front

What is the importance of understanding remainders in real-life situations?

Back

Understanding remainders helps in making decisions about resources, such as how many trips to take or how to divide items.

Front

How do you determine the number of complete boxes you can make with a set number of items?
