Answer:
The correct answer is 52 squats.
Step-by-step explanation:
An exercise routine requires 24 crunches for every 16 squats.
Therefore the routine would require 1 crunch for every [tex]\frac{16}{24}[/tex] squats.
And by the use of unitary method, the routine would require 78 crunches for every [tex]\frac{16}{24}[/tex] × 78 squats = 52 squats.
Thus for every 78 crunches attempted, the exercise routine would requires 52 squats to be done.
