Percent means "divide by 100", "of" in Math means to "multiply", and "is" means "equal." Lets write what we know into an equation to make this easier.
36 = ?% x 80
We know that something x something equals a number, but we also know that the number divided by one something gives us the other something. Follow? If something % x 80 = 36, then 36 divided by 80 gives us the percent to fill in the question mark (when we multiply by 100). 36 divided by 80 = .45, or 45%
Check your work by finding 45% of 80. 80 x .45 = 36, so our answer is correct.
125 - (36%) = 80
Solve this problem -x squared -40x- 80 =0
What you do is divide 80, or any number, by 100 then multiply by the percent you need, like 80, and there's your answer. Example (Your problem): 80/100=0.8 0.8x80=64 So your answer: 80% of 80 is 64
24 percent is another way of writing 0.24 Simply replace "of" with "times", and you get 0.24 times 80 Solve, and you get: 0.24 times 80 = 19.2
50% of 80 = 40 because 50% = 0.5 0.5 x 80 = 40 or you can divide 40 by 0.5 40/0.5 = 80
36 is what percent of 80:= 36 / 80= 0.45Converting decimal to a percentage: 0.45 * 100 = 45%
80% of 36 = 36*80/100 = 28.8
80 percent of 45 percent = 0.8 x 45 percent = 36 percent
36/0.8 = 45. Therefore, the number that 36 is 80 percent of, is 45.
answer is 36
45 percent of 80 = 36

80 times .9
80
80 percent of 45 people = 36 people.
Expressed as a percentage, 36/80 x 100 = 45 percent.
