Question

A relay race is over 1 1/2 kilometers, and each runner on a team will run 1/4 of a kilometer. How many runners are needed for a team?

Answer 1

Conversion: 1 1/2 = 1•2+1= 3/2

———

2

Divide: 3/2 by 1/4 = 3/2 • 4/1 = 12/2 = 6

To divide one fraction by another, invert (turn upside-down) the second fraction, then multiply.

Or change to %

1 1/2 = 150% 1/4 = 25%

150 divided by 25 = 6

Answer 2

Number of runners needed = 1 1/2 / 1/4

= 3/2 / 1/4

= 3/2 * 4

= 12/2 = 6 runners (answer).
