How do you calculate a percentage?

Answer 1

To calculate percentages, just divide the part by the total and multiply by 100.

Example: What percentage of 45 is 6? Find 6/45 and multiply it by 100. This gives you 131/3%.

Remember that the "part" can also represent numbers larger than the whole, which gives you a percentage high than 100.

You can also reverse this to find a number instead of a percentage.

Example: What is 35% of 60? Divide 60 by 100 and multiply it by 35. This gives you 21.

It is easier to do this, however, if you multiply the whole by a decimal.

Example: What is 60% of 20? Just multiply 20 by .6, which gives you 12.

Lastly, given a part and the percentage of a whole it represents, you can find the whole by dividing the part by the percentage (in decimal form).

Example: What number is 13 80% of? Divide 13 by .8 to get your answer: 161/4.

sometimes doing percentages are hard so just my easy steps above

Good question, but the question is, percentage of what?

percentage of the total

What i mean by this is working out a percentage of a total of something . So if you wanted to know what percentage of apples are green and what are red for example:

green: 32

red: 59

add them together = 91

for the percentage of green apples = number of green apples / total number of

apples number x 100

so, 32 / 91 = 0.3516 x 100 = 35.16%

Percentage of eachother

How to work out how many green apples there are in relation to red=

32 / 59 x 100 = 54.24%

Percentage increase of green apples to red

59 - 32 = 27

27 / 32 x 100 = 84.37%

there are quite a few variations

Answer 2

To calculate a percentage you have to take the difference of two numbers over the originals and multiply by 100.
