Question

When Richard works out, he spends 12 minutes doing cardio and 18 minutes doing resistance training. Cooper's workout consists of 10 minutes of cardio and 16 minutes of resistance training. Who does a higher ratio of cardio to resistance training?

Answer 1

Answer:

Richard, at 2/3, versus Cooper, at 5/8

Step-by-step explanation:                              12 min

Richard's ratio of cardio to resistance is  R = ------------ = 2/3

                                                                            18 min

                            10 min

Cooper's is  C = ------------ = 5/8

                            16 min

The LCD here is 24.  Rewrite 2/3 and 5/8 with denominator 24 for greater ease in comparing the two fractions/ratios:

R = 16/24 and C = 15/24

So it becomes obvious that Richard does a higher ratio of carido to resistance.
