'is' in mathematics means equal
'of' in mathematics means multiplication
Translating 8 is 50% of what number into an equation, we get:
8 = 50% x
50%, or 50 percent, is nothing but 50 over 100 or 50/100, which is the same as 1/2.
8 = 1/2 x
Multiply 2 on both sides.
8 2 = 1/2 2 * x
16 = x
x = 16
8 is 50% of 16.
