Answer:

70% of 130 = 91

Explanation:

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#
