#### Method 1: Diagonal multiplication to calculate 90 percent of 93.

- For 100, our answer will be 90
- For 93, our answer will be x
- 100*x = 90*93 (In Step 1 and 2 see colored text; Diagonal multiplications will always be equal)
- x = 90*93/100 = 8370/100 = 83.7

#### Answer: 90 percent of 93 is 83.7

- For 100, our answer will be 90
- For 93, our answer will be x
- 100/93 = 90/x (In Step 1 and 2, see colored text; Same side divisions will always be equal)
- 90/x = 100/93 or x/90 = 93/100
- x = 93*90/100 = 8370/100 = 83.7

#### Answer: 90 percent of 93 is 83.7

#### Method 3: Converting Percentage to Decimal to calculate 90 percent of 93

- Find the decimal equivalent of 90 i.e. 90/100 = 0.9

### 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. 90% (read as 90 percent) can also be expressed as 90/100 or 90:100.Example: If 90% (90 percent) of your savings are invested in stocks, then 90 out of every 100 dollars are invested in stocks. If your savings are $10,000, then a total of 90*100 (i.e. $9000) are invested in stocks.

### History of Percentage

Before the Europeans learned about the decimal system, ancient Romans used fractions in the multiples of 1/100. An example was when Augustus levied a tax of 1/100 called centesima rerum venalium on goods sold at auctions. Computation with these fractions was similar to percentages.In the Middle Ages, denominator of 100 became more common. By the 16th century, as decimal system became more common, use of percentage became a standard. It was used to compute profit and loss, interest rates etc.
