Answer:

85%

Step-by-step explanation:

There is a formula for solving for percentages:

part/whole=%/100

So, Evelyn got a 17/20, yes? The when you plug in the info yo have you get:

17/20=x/100

The next step is that you criss-cross multiply, then divide. So you'd take whatever top number is there and multiply it with the 100.

17x100=1700   1700/20=85

I hope that makes sense!
