Question

1. The fastest speed recorded for a runner is 27 miles per hour. This is 20% of the fastest speed for a water skier. Find the record for a water skier.

____Mph
2. Bowsers dog food is 60% meat. If Bowser needs 24 oz of meat each week, how many ounces of dog food should he eat? ____oz

Answer 1

To get the answer we have to use proportion
20% -----------------27
100% --------------x
crossmultiply now
20*x=100*27 /:20
x=2700:20
x=135 miles/hour

Similar situation
60% --------------24
100% -------------x
crossmultiply
60*x=100*24
60x=2400 /:60
x=40 - its the answer
