over y equals 56.
Now let's get that twisted denominator y on top as a numerator, and multiply both sides
by y... to get 100y over y equals 56y.
Why? Because we said so.
So that's 100y on the left and 56y on the right
Divide both sides by 56 and we have y equals 100 over 56.
Now time to reduce. Thank you, Curves.
Both numbers are even, so we know we can divide by 2... which gives us 50 over 28.
Whoops... still even. So divide by 2 again and we have 25 over 14.
Boom. The answer is D.
