70% of 130 = 91

Let's call the percent we are looking for $n%$ . "Percent" or "%" means "out of 100" or "per 100", Therefore n% can be written as $n/100$ .

When dealing with percents the word "of" means "times" or "to multiply".

Putting this altogether we can write this equation and solve for $n$ while keeping the equation balanced:

$n/100 xx 130 = 91$

$(n xx 130)/100 = 91$

$100/130 xx (n xx 130)/100 = 100/130 xx 91$

$cancel(100)/cancel(130) xx (n xx cancel(130))/cancel(100) = 9100/130$

$n = 9100/130$

$n = 70$
