hi there! the answer and explanation is...
Percentage is out of 100, so we can set up a proportion with 25/121 = x/100. Solve for x by cross multiplying.
25*100 = 121x
x = 2500/121 = 20.661%
Do the same thing for the next one.
121/25 = x/100
121*100 = 25x
x = 12100/25 = 484%
hope this helped! have a good one!
