You can re-express this as:
50 / 80 = x / 100
and then solve for x:
8x = 500
x = 125/2
x = 62.5
So 50 is 62.5 percent of 80.
Percent decrease is when your overall percentage goes down. Example: I take a 4 problem math test and get one wrong, 75%. I take a 2 problem math test and get one wrong, 50%.
100*30/35 = 85.7142857... %
ANSWER: 24 percent% rate:= 120/500 * 100%= 0.24 * 100%= 24%
Whenever you see "what number" use a variable. I like to use the variable "a". First, change 5 percent to a decimal. Do this by taking the percent (5) and dividing it by 100. You will get 0.05. Set your problem up. Whenever you see "is" in a math problem think of an = sign. Whenever you see "of" in a math problem think of multiplying so, what number is 5 percent of 82, a = 0.05 x 82, a=4.1.
per, a out of ratio of, quotient of percent (divide by 100)
x% = x/100 = x:100 if x happens to have a common factor with 100, then simplify it. it is as easy as that. for example, 28% = 28/100 = 7:25 25% = 25/100 = 1:4

any number divided by hundred for ex: 5/100
equality of two ratios is called proportion.
68 percent of 13 = 8.84 68% of 13=68% * 13 = 0.68 * 13 = 8.84
Multiply the number by the percent in decimal form, and subtract the result from the original number. Alternatively, multiply the number by (1 - the percent).

2 1/3 To translate English to math, the phrase "a of b" means a/b. In this case the problem is 56/24 which is 2.33.
