37.9 is what percent of 630 - 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 630 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 630, so we can write it down as 100%=630.
4. We know, that x% equals 37.9 of the output value, so we can write it down as x%=37.9.
5. Now we have two simple equations:
1) 100%=630
2) x%=37.9
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%=630/37.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 37.9 is what percent of 630

100%/x%=630/37.9
(100/x)*x=(630/37.9)*x       - we multiply both sides of the equation by x
100=16.622691292876*x       - we divide both sides of the equation by (16.622691292876) to get x
100/16.622691292876=x
6.015873015873=x
x=6.015873015873

now we have:
37.9 is 6.015873015873% of 630
