First, let's organise the info and use algebra!

Let x represent the number of sit ups Abby can do in a minute.

121 sit ups = 8 minutes
  x sit ups       1 minute

x sit ups = 121 sit ups x 1 minute ÷ 8 minutes
x sit ups = 15.125
x sit ups = ~15

Therefore, Abby can do ~15 sit ups in one minute.

Hope this helps!

Abby most likely did 15 sit-ups in 1 minute because 121 divided by 8 equals 15.125 and if you round that you get 15 sit-ups.
