212.9 is what percent of 370 - 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 370 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 370, so we can write it down as 100%=370.
4. We know, that x% equals 212.9 of the output value, so we can write it down as x%=212.9.
5. Now we have two simple equations:
1) 100%=370
2) x%=212.9
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%=370/212.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 212.9 is what percent of 370

100%/x%=370/212.9
(100/x)*x=(370/212.9)*x       - we multiply both sides of the equation by x
100=1.7379051197745*x       - we divide both sides of the equation by (1.7379051197745) to get x
100/1.7379051197745=x
57.540540540541=x
x=57.540540540541

now we have:
212.9 is 57.540540540541% of 370
