Dividing a Unit Fraction by a Whole Number Using the Number Line

The video tutorial explains how to solve a problem involving a relay race where Finn and his friends run a total distance of 1/2 mile. The problem is broken down into dividing the total distance by four, as each person runs an equal part. The solution is visualized using a number line, showing that each person runs 1/8 mile. The solution is verified by multiplying the quotient by the divisor to ensure it equals the original distance. The lesson concludes with a summary of dividing fractions by whole numbers using a number line.

Finn and his friends are running a relay race that is 1/2 mile long. How should the distance be divided among them?

• Each person runs 1/4 mile

• Each person runs 1/8 mile

• Each person runs 1/2 mile

• Each person runs 1 mile

What is the first step in using a number line to divide 1/2 mile into four equal parts?

• Draw a line from 0 to 1/2

• Draw a line from 0 to 1/4

• Draw a line from 0 to 1

• Draw a line from 0 to 1/8

How many parts make up the whole when dividing 1/2 mile into four equal parts on a number line?

• Four parts

• Ten parts

• Six parts

• Eight parts

What is the product of multiplying 1/8 by 4?

• 1/2

• 2

• 1/4

• 1

Why do we rewrite 4 as 4/1 when verifying the division?

• To perform fraction multiplication

• To convert it to a decimal

• To simplify the fraction

• To make it easier to add
