if in 3 minutes you can do 45 sit-ups, how much can you do in 1 minutes?

Answer :

First let's determine the number of squats per minute by finding the ratio of the number of squats per minute.

[tex]r=\frac{45\text{ sit ups}}{3\text{ min}}=15\text{ sit-up per minute }[/tex]

This means that you can do 15 sit-ups in one minute.
