How do you find what percent one number is of another?

Question

There is this "is over of" method using proportions that someone showed me once. How does that work?

Answer 1

You take the qualifying number and divide it by the total number, then multiply the product by 100%.

A simple example:

There are 48 cars on a lot and 13 of them are blue.

Divide: 13/48 = 0.2708333.... We'll round to 0.27.

Multiply by 100%: 0.27 X 100% = 27%

27% of the cars on the lot are blue.

what percent of 40 is 24 x percent of 40 is 24 x percent means x/100 of means multiplication is means equal to x/100 × 40 = 24 or 40x/100 = 24 x = 24 × 100/40 x = 60 55 is 20% of what number 55 is 20% of x 55 = 20/100 × x x = 55 × 100/20 = 275 what number is 30% of 210 x is 30% of 210 x = 30/100 × 210 = 63 ----

Answer 3

If you want to find out the percentage that 20 is of 100 for example, write the numbers as a fraction:
20/100=2/10=1/5 then divide one by five and the percentage is 20.
So if you want to know what percent X is of Y write it as a fraction, X/Y and divide X by Y the resulting dividend is your percentage.

Answer 4

Example: 5 is what percent of 20?

Divide 5 by 20

Answer: .25 ( 25% )

Answer 5

How Do You Find Percent

Answer 6

Formula

Amount = Base x Percent

- - - - - - - - - -

Fing the amount when the base and percent are known.

75 percent of 8 gives what amount

First convert 75% to decimal

first remove the % sign and divide by 100

75/100 = 0.75

Multiply 8 by the decimal

8 x 0.75 = 6

The amount is 6

- - - - - - - - - - -

finding the base when the amount and percent are known

Amount / Percent = base

first convert 75% to decimal

first remove the % sign. divide 75 by 100

75/100 = 0.75

Divide the amount by the decimal

6 / 0.75 = 8

The base is 8

- - - - - - - - - - - - - - - -

Finding the percent when the amount and base are known.

Amount / base = Percent

6 is what percent of 8

divide 6 by 8

6 / 8 = 0,75

Convert the decimal to percent

Multiply the decimal by 100 and attact the % sign

0.75 x 100 = 75%

The percent is 75%

Answer 8

example: 5 is what percent of 20?

the "over of" method you suggest is possibly like this....

5/20 = x/100

since it is an equation, if we DO ANYTHING to it, we need to do the SAME thing to both sides, so it stays balanced, like a scale. Sorry if that is too pedantic. :-)

In this example, multiply both sides by 100 to try to ge the "x" alone.

100 * (5/20) = (x/100) * 100

doing the arithmetic...

5 * 5 = x

so 25 = x, and that is your answer!

5 is 25% of 20.

yay!

Answer 10

X% = X/100, by the definition.

Indeed, "percent" is surely derived from Latin for "per hundred", where "per" is itself Latin and means something like from, out of, or according to.
