A percentage can be written as a value divided by 100, so assume that this percentage is \(\frac{x}{100}\). In most of these equations, "of" refers to multiplication, while "is" refers to equals. So you can rewrite the equation in terms of math, \(\frac{x}{100}*150=75\). So first, you can simplify the \(\frac{150x}{100}\) on the left side to \(\frac{3x}{2}\) by dividing both the numerator and denominator by 50. So now multiply both sides by 2 and divide by 3. \(3x=75(2)=150\) then \(3x=150, x=50\). So 50 percent of 150 is 75.
