### 18 is 10 percent of 180. Explanation: What does 10 percent or 10% mean?

Percent (%) is an abbreviation for the Latin “per centum”, which means per hundred or for every hundred. So, 10% means 10 out of every 100.

### Methods to calculate "18 is 10 percent of what number" with step by step explanation:

#### Method 1: Diagonal multiplication to calculate "18 is 10 percent of what number".

- As given: For 10, our answer will be 100
- Assume: For 18, our answer will be X
- 10*X = 100*18 (In Steps 1 and 2 see colored text; Diagonal multiplications will always be equal)
- X = 100*18/10 = 1800/10 = 180

#### 18 is 10 percent of 180

#### Method 2: Same side division to calculate "18 is 10 percent of what number".

- As given: For 10, our answer will be 100
- Assume: For 18, our answer will be X
- 100/x = 10/18 (In Step 1 and 2, see colored text; Same side divisions will always be equal)
- 100/X = 10/18 or x/100 = 18/10
- X = 18*100/18 = 1800/10 = 180

#### 18 is 10 percent of 180

### 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. 18% (read as 18 percent) can also be expressed as 18/100 or 18:100.Example: If 18% (18 percent) of your savings are invested in stocks, then 18 out of every 100 dollars are invested in stocks. If your savings are $10,000, then a total of 18*100 (i.e. $1800) are invested in stocks.

### Percentage sign (%)

The percent (per cent i.e. per hundred) sign % is the standard symbol to indicate a percentage, to signify a number or ratio as a fraction of 100. Related signs include the permille (per thousand) sign ‰ and the permyriad (per ten thousand) sign ‱ (also known as a basis point), which indicate that a number is divided by one thousand or ten thousand, respectively.### Scholarship programs to learn math
