22 is what percent of 247.5 - 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 247.5 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 247.5, so we can write it down as 100%=247.5.
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%=247.5
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%=247.5/22
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 247.5

100%/x%=247.5/22
(100/x)*x=(247.5/22)*x       - we multiply both sides of the equation by x
100=11.25*x       - we divide both sides of the equation by (11.25) to get x
100/11.25=x
8.8888888888889=x
x=8.8888888888889

now we have:
22 is 8.8888888888889% of 247.5
