How do you calculate percentage?

Answer 1

Number divided by Number times 100.

Examples:

Someone shoots 10 baskets and they make 5. 5 / 10 = 0.50 * 100 = 50%

They made 50% of their shots.

Someone bets $5 and they win $5. They ended with $10 divided by the $5 they started with, $10 / $5 = 2.0 * 100 = 200%

They now have 200% of what they started with.

Those examples are not great, but maybe it'll get you what you need. turn it to a decimal by putting the number on top in the house and move the decimal to the right 2 times

Answer 2

Percent is derived from the Latin words "per" meaning "through" or "during"/"throughout" and "cent" meaning "hundred" - the same derivation as the French word "cent" or the Spanish word "ciento", and the English word "century".

How to calculate percentages depends what kind of question you are given. If you are given a question such as: "8 is what percent of 32?", you do the following calculation:

8/32 x 100 = 25

Therefore, 8 is 25 percent of 32.

Percentage increases and decreases can be handled slightly differently. For example, if you are asked a question like, "What is 60 plus ten percent?" you can either multiply by 110/100, or, more efficiently, by 1.1. In this instance, 60 + 10% = 60 x 1.1 = 66.

If you are asked a question such as "What is 60 minus ten percent?" you can either multiply by 90/100, or, more efficiently, by 0.9. In this instance, 60 - 10% = 60 x 0.9 = 54. While most percentage increase or decrease questions can be dressed up to incorporate a particular situation, the mathematics more-or-less always uses one of these two methods.

If you are asked a question such as "What percentage of 40 is 10", you can work this out by saying 10/40 x 100. This works even with percentages over 100, for example, "What percentage of 40 is 50?", you can work this out by saying 50/40 x 100 = 120 percent.
