See the entire solution process below:

Explanation:

Let's call the percent we are looking for pp.

"Percent" or "%" means "out of 100" or "per 100", Therefore p% can be written as p/100p100.

So we can write and solve for pp:

p/100 = 36/90p100=3690

color(red)(100) * p/100 = color(red)(100) * 36/90100p100=1003690

cancel(color(red)(100)) * p/color(red)(cancel(color(black)(100))) = 3600/90

p = 40

color(red)(40%) of 90 is 36
