### Methods to calculate "3 is 3 percent of what number" with step by step explanation:

#### Method 1: Diagonal multiplication to calculate "3 is 3 percent of what number".

- As given: For 3, our answer will be 100
- Assume: For 3, our answer will be X
- 3*X = 100*3 (In Steps 1 and 2 see colored text; Diagonal multiplications will always be equal)
- X = 100*3/3 = 300/3 = 100

#### 3 is 3 percent of 100

#### Method 2: Same side division to calculate "3 is 3 percent of what number".

- As given: For 3, our answer will be 100
- Assume: For 3, our answer will be X
- 100/x = 3/3 (In Step 1 and 2, see colored text; Same side divisions will always be equal)
- 100/X = 3/3 or x/100 = 3/3
- X = 3*100/3 = 300/3 = 100

#### 3 is 3 percent of 100

### 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. 3% (read as 3 percent) can also be expressed as 3/100 or 3:100.Example: If 3% (3 percent) of your savings are invested in stocks, then 3 out of every 100 dollars are invested in stocks. If your savings are $10,000, then a total of 3*100 (i.e. $300) are invested in stocks.

- 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%
