Answer:

20

Explanation:

Steps to solve "9 is 45 percent of what number?"

We have, 45% × x = 9

or,

45

100

× x = 9

Multiplying both sides by 100 and dividing both sides by 45,

we have x = 9 ×

100

45

x = 20

If you are using a calculator, simply enter 9×100÷45, which will give you the answer.
