22 is what percent of 290 - 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 290 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 290, so we can write it down as 100%=290.
4. We know, that x% equals 22 of the output value, so we can write it down as x%=22.
5. Now we have two simple equations:
1) 100%=290
2) x%=22
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%=290/22
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 22 is what percent of 290

100%/x%=290/22
(100/x)*x=(290/22)*x       - we multiply both sides of the equation by x
100=13.181818181818*x       - we divide both sides of the equation by (13.181818181818) to get x
100/13.181818181818=x
7.5862068965517=x
x=7.5862068965517

now we have:
22 is 7.5862068965517% of 290
