1 9 % * 2 0 =

### 2. If your calculator does not have a “%” button

Step 1: Remove the percent sign and add a couple of zeros after the decimal point.
19% becomes 19.00
Step 2: Convert the percent to a decimal by moving the decimal point two places to the left:
19.00 > .1900
Step 3: Press these buttons:

. 1 9 * 2 0 =

### A different type of question

19 is what percentage of 20?
Step 1: Rewrite the question as a fraction. “19 out of 20” becomes:
19/20.
Step 2: Multiply Step 1 by 100:
(19/20) * 100 = 95
