what percent of 80 is 42?

Answer 1

find the percent when the base and amount are known

amount / base = percent

let

42 = amount

80 = base

Divide 42 by 80 to get percent

42 / 80 = 0.525

Multiply the decimal by 100 and attach the % symbol

0.525 x 100 = 52.5 %

42 is 52.5 % of 80

Answer 2

There is a simple trick to doing problems like this. All you have to do is learn this key:

what = n
percent = #/100
is = "="
of = x (times)

So...
what percent of 80 is 42 turns into...
(n/100) x (80) = 42

Solving for n produces

(42/80) x (100) which is equal to 52.5












Here's another one you can practice to make sure you understand. (the answer is below, don't scroll down too far!)


80 is what percent of 682?













80 = (n/100) x (682)

n = (80/682) x (100) = approximately 11.73

Good luck, this trick will be helpful for things like the SAT, so be sure to learn it.
