See the solution process below:

Explanation:

First, let's call the percent we are looking for p

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

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

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

p/100 xx 180 = 120

color(red)(100)/color(blue)(180) * p/100 xx 180 = color(red)(100)/color(blue)(180) * 120

cancel(color(red)(100))/cancel(color(blue)(180)) * p/color(red)(cancel(color(black)(100))) xx color(blue)(cancel(color(black)(180))) = 12000/color(blue)(180)

p = 66.bar6

120 is 66.bar6% or 66 2/3% of 180.

66.bar6%

Explanation:

You take 120 over 180 and times it by 100% to get the percentage.

(120/180)=0.bar6

0.bar6 xx 100%=66.bar6%
