Dividing Whole Numbers by Fractions

This video tutorial explains how to compute a quotient by dividing a whole number by a fraction. It addresses common misunderstandings and emphasizes the importance of context in division problems. Through examples involving a track and a cookie recipe, the tutorial demonstrates how to interpret division problems by writing stories and asking clarifying questions. The video concludes by reinforcing the concept of viewing division problems in context to make them more understandable.

What is a common misunderstanding when dividing a whole number by a fraction?

• The quotient is always smaller.

• The quotient is always larger.

• The divisor must be a whole number.

• The dividend must be a fraction.

What is the first step in understanding a division problem involving fractions?

• Convert the fraction to a decimal.

• Multiply the numbers involved.

• Write a story to provide context.

• Calculate the quotient directly.

In the track story problem, how many laps are there in 5 miles?

• 15 laps

• 25 laps

• 10 laps

• 20 laps

How many recipes can Jesse make with 4 bags of chocolate chips if each recipe requires 1/3 of a bag?

• 14 recipes

• 12 recipes

• 10 recipes

• 8 recipes

In the cookie recipe example, what is the divisor when each recipe requires 1/3 of a bag?

• 1/2

• 1/3

• 1/4

• 1/5

If Jesse's recipe changes to require 2/3 of a bag, how many recipes can he make with 4 bags?

• 4 recipes

• 6 recipes

• 7 recipes

• 5 recipes

Why is it important to view division problems in context?

• To avoid using fractions.

• To make the problem more complex.

• To ensure the quotient is always larger.

• To make the problem easier to understand.
