Dividing Fractions and Whole Numbers

Front

What is the process of dividing a whole number by a fraction?

Back

To divide a whole number by a fraction, multiply the whole number by the reciprocal of the fraction. For example, to divide 5 by 1/6, calculate 5 * (6/1) = 30.

How do you find the total number of items when dividing a quantity into smaller parts?

Back

To find the total number of items, divide the total quantity by the size of each part. For example, if you have 9 apples and each friend gets 1/2 an apple, you calculate 9 ÷ (1/2) = 18.

What is a reciprocal in mathematics?

Back

A reciprocal of a number is 1 divided by that number. For example, the reciprocal of 1/4 is 4/1.

What is the formula for finding the number of slices when dividing a whole into smaller fractions?

Back

The formula is: Total slices = Total whole items × (1 ÷ size of each slice). For example, 4 pizzas divided into 1/4 slices gives 4 × (1 ÷ 1/4) = 16 slices.
