9.21 is what percent of 22.99 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 22.99 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 22.99, so we can write it down as 100%=22.99.
4. We know, that x% equals 9.21 of the output value, so we can write it down as x%=9.21.
5. Now we have two simple equations:
1) 100%=22.99
2) x%=9.21
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=22.99/9.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.21 is what percent of 22.99

100%/x%=22.99/9.21
(100/x)*x=(22.99/9.21)*x       - we multiply both sides of the equation by x
100=2.4961997828447*x       - we divide both sides of the equation by (2.4961997828447) to get x
100/2.4961997828447=x
40.060896041757=x
x=40.060896041757

now we have:
9.21 is 40.060896041757% of 22.99
