Evaluate the following percent problem
9 is 45 percent (%) of what number?
Set up an equation
Let's call our missing number x.
Expressing this in terms of an equation, we get:
9 = 45% * x
Express this as a percentage
Percentage = percent number/100
| 9 = | 45x |
| 100 |
Multiply both sides by 100
| 9 * 100 = | 45 * 100x |
| 100 |
900 = 45x
Divide each side by 45
| 900 |
| 45 |
| = |
| 45x |
| 45 |
Cancel both 45
| 900 |
| 45 |
| = |
| x = | 900 |
| 45 |
Final Answer
