37 is what percent of 215 - 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 215 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 215, so we can write it down as 100%=215.
4. We know, that x% equals 37 of the output value, so we can write it down as x%=37.
5. Now we have two simple equations:
1) 100%=215
2) x%=37
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%=215/37
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 37 is what percent of 215

100%/x%=215/37
(100/x)*x=(215/37)*x       - we multiply both sides of the equation by x
100=5.8108108108108*x       - we divide both sides of the equation by (5.8108108108108) to get x
100/5.8108108108108=x
17.209302325581=x
x=17.209302325581

now we have:
37 is 17.209302325581% of 215
