34.21 is what percent of 1390.51 - 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 1390.51 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 1390.51, so we can write it down as 100%=1390.51.
4. We know, that x% equals 34.21 of the output value, so we can write it down as x%=34.21.
5. Now we have two simple equations:
1) 100%=1390.51
2) x%=34.21
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%=1390.51/34.21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 34.21 is what percent of 1390.51

100%/x%=1390.51/34.21
(100/x)*x=(1390.51/34.21)*x       - we multiply both sides of the equation by x
100=40.646302250804*x       - we divide both sides of the equation by (40.646302250804) to get x
100/40.646302250804=x
2.4602483980698=x
x=2.4602483980698

now we have:
34.21 is 2.4602483980698% of 1390.51
