Calculating percentages can be an easy task. There are numerous percentage calculators online that can help with task by simply searching for “percentage calculator.” However, there may be a time when (however, unlikely it sounds) you may need to be able to calculate percentages without any digital assistance.

Before you can start, you should first understand exactly what a percentage is.

The word percentage comes from the word percent. In the event that you split the word percent into its root words, you see “per” and cent.” Cent is an old European word with French, Latin, and Italian starting points signifying “hundred”. In this way, percent is made an interpretation of legitimately to “per hundred.” If you have 87 percent, you actually have 87 for each 100. In the event that it snowed 13 times over the most recent 100 days, it snowed 13 percent of the time. 

The numbers that you will change over into rates can be given to you in 2 distinct arrangements, decimal and portion. Decimal organization is simpler to figure into a rate. Changing over a decimal to a rate is as basic as duplicating it by 100. To change over .87 to a percent, just various .87 by 100. 

Example

.87 × 100=87

Thus, resulting in 87 percent.

If you are given a fraction, convert it to a percentage by dividing the top number by the bottom number. If you are given 13/100, you would divide 13 by 100.

13 ÷ 100 = .13

Then, follow the steps above for converting a decimal to a percent.

13 × 100 = 13 

Accordingly getting 13%. 

Example

The more troublesome errand comes when you have to know a rate when you are given numbers that don’t fit so conveniently into 100. 

More often than not, you will be given a level of a given number. For instance, you may realize that 40 percent of your check will go to expenses and you need to discover how a lot of cash that is. To figure the level of a particular number, you first convert the rate number to a decimal. 

This procedure is the turn around of what you did before. You isolate your rate by 100. Along these lines, 40% would be 40 separated by 100 or .40.

40 ÷ 100 = .40 

When you have the decimal variant of your rate, basically duplicate it by the given number. For this situation, the measure of your check. On the off chance that your check is $750, you would increase 750 by .40. 

750 × .40 = 300 

Your answer would be 300. You are making good on $300 in regulatory obligations. 

We should attempt another model. You have to spare 25 percent of your check for the following a half year to pay for an up and coming get-away. In the event that your check is $1500, what amount would it be advisable for you to spare? 

Start by changing over 25 percent to a decimal. 

25 ÷ 100 = .25 

Presently, increase the decimal by the measure of your check, or 1500. 

1500 × .25 = 375 

You have to spare $375 from every check.
