Front

What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 divided by 3 (12 ÷ 3) means splitting 12 into 3 equal parts, which equals 4.

How do you find the total number of items when given the number of groups and items per group?

Back

Multiply the number of groups by the number of items in each group. For example, if there are 5 groups with 4 items each, the total is 5 x 4 = 20.

Front

What is the formula for finding the number of items in each group when the total and number of groups are known?

Back

Divide the total number of items by the number of groups. For example, if there are 60 items in 5 groups, each group has 60 ÷ 5 = 12 items.

Front

If a car travels 300 miles using 10 gallons of fuel, how do you find the miles per gallon?

Back

Divide the total miles traveled by the total gallons used. In this case, 300 miles ÷ 10 gallons = 30 miles per gallon.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If you multiply a number by another, you can divide the result by the same number to get back the original number.

Front

How can you check your multiplication answer?

Back

You can check your multiplication answer by using division. For example, if you calculated 4 x 5 = 20, you can check by dividing 20 by 5 to see if you get 4.

Front

What does it mean to divide equally?

Back

Front

What is a batch in baking?

Back

A batch in baking refers to a specific quantity of items made at one time. For example, if a baker makes 2 batches of cookies, the total number of cookies is the sum of the cookies in each batch.

Front

How do you calculate the total cost of multiple items?

Back

Multiply the cost of one item by the number of items purchased. For example, if one book costs $15 and you buy 4 books, the total cost is 15 x 4 = $60.
