Dividing Whole Numbers and Fractions

This lesson teaches how to interpret remainders when dividing fractions using models. It begins with a review of dividing whole numbers and understanding remainders. The lesson then explains how to divide by fractions, using models to visualize the process. Two examples are provided: dividing 2/3 by 1/2 and 5/8 by 1/2, demonstrating how to interpret remainders as fractions of the divisor. The lesson concludes with checking answers by multiplying by the reciprocal.

What does it mean when you divide a whole number by another whole number, like 7 divided by 2?

• The sum of 7 and 2

• How many times 2 fits into 7

• The difference between 7 and 2

• How many times 7 fits into 2

When dividing 1 by 1/2, how many groups of 1/2 are in 1 whole?

• 2 groups

• 1 group

• 3 groups

• 4 groups

In the example of dividing 2/3 by 1/2, what is the remainder expressed as?
