121.7 is what percent of 540 - 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 540 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 540, so we can write it down as 100%=540.
4. We know, that x% equals 121.7 of the output value, so we can write it down as x%=121.7.
5. Now we have two simple equations:
1) 100%=540
2) x%=121.7
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%=540/121.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 121.7 is what percent of 540

100%/x%=540/121.7
(100/x)*x=(540/121.7)*x       - we multiply both sides of the equation by x
100=4.4371405094495*x       - we divide both sides of the equation by (4.4371405094495) to get x
100/4.4371405094495=x
22.537037037037=x
x=22.537037037037

now we have:
121.7 is 22.537037037037% of 540
