68.6 is what percent of 45 - 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 45 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 45, so we can write it down as 100%=45.
4. We know, that x% equals 68.6 of the output value, so we can write it down as x%=68.6.
5. Now we have two simple equations:
1) 100%=45
2) x%=68.6
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%=45/68.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 68.6 is what percent of 45

100%/x%=45/68.6
(100/x)*x=(45/68.6)*x       - we multiply both sides of the equation by x
100=0.65597667638484*x       - we divide both sides of the equation by (0.65597667638484) to get x
100/0.65597667638484=x
152.44444444444=x
x=152.44444444444

now we have:
68.6 is 152.44444444444% of 45
