Arelay 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?

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

= 3/2  /   1/4

= 3/2  *  4

= 12/2  = 6  runners (answer).

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
