"of' is multiplication.
"is" is equal.
So x% of 50 is 35 could be written as
x%

50 = 35
The first step is to divide by 50 on both sides.
x% times 50 divided by 50 is x%.
35 divided by 50 is .7
So x% = .7.
The next step is to get rid of the percent sign to find the value of x (our answer). To do this, we multiply by 100 on both sides.
x% times 100 is x.
.7 times 100 is 70%.
So x = 70%.
The answer:
70% of 50 shirts is 35 shirts.
