Percent (%) is an abbreviation for the Latin “per centum”, which means per hundred or for every hundred. So, 5% means 5 out of every 100.

### Methods to calculate "4 is 5 percent of what number" with step by step explanation:

#### Method 1: Diagonal multiplication to calculate "4 is 5 percent of what number".

- As given: For 5, our answer will be 100
- Assume: For 4, our answer will be X
- 5*X = 100*4 (In Steps 1 and 2 see colored text; Diagonal multiplications will always be equal)
- X = 100*4/5 = 400/5 = 80

#### 4 is 5 percent of 80

#### Method 2: Same side division to calculate "4 is 5 percent of what number".

- As given: For 5, our answer will be 100
- Assume: For 4, our answer will be X
- 100/x = 5/4 (In Step 1 and 2, see colored text; Same side divisions will always be equal)
- 100/X = 5/4 or x/100 = 4/5
- X = 4*100/4 = 400/5 = 80

#### 4 is 5 percent of 80

### Percentage examples

Percentages express a proportionate part of a total. When a total is not given then it is assumed to be 100. E.g. 4% (read as 4 percent) can also be expressed as 4/100 or 4:100.Example: If 4% (4 percent) of your savings are invested in stocks, then 4 out of every 100 dollars are invested in stocks. If your savings are $10,000, then a total of 4*100 (i.e. $400) are invested in stocks.

- To find 5%, find 10% and divide it by two
- To find 11%, find 10%, then find 1%, then add both values
- To find 15%, find 10%, then add 5%
- To find 20%, find 10% and double it
- To find 25%, find 50% and then halve it
- To find 26%, find 25% as above, then find 1%, and then add these two values
- To find 60%, find 50% and add 10%
- To find 75%, find 50% and add 25%
- To find 95%, find 5% and then deduct it from the number
