38.7 is what percent of 168 - 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 168 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 168, so we can write it down as 100%=168.
4. We know, that x% equals 38.7 of the output value, so we can write it down as x%=38.7.
5. Now we have two simple equations:
1) 100%=168
2) x%=38.7
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%=168/38.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38.7 is what percent of 168

100%/x%=168/38.7
(100/x)*x=(168/38.7)*x       - we multiply both sides of the equation by x
100=4.3410852713178*x       - we divide both sides of the equation by (4.3410852713178) to get x
100/4.3410852713178=x
23.035714285714=x
x=23.035714285714

now we have:
38.7 is 23.035714285714% of 168
