20.37 is what percent of 780 - 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 780 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 780, so we can write it down as 100%=780.
4. We know, that x% equals 20.37 of the output value, so we can write it down as x%=20.37.
5. Now we have two simple equations:
1) 100%=780
2) x%=20.37
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%=780/20.37
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.37 is what percent of 780

100%/x%=780/20.37
(100/x)*x=(780/20.37)*x       - we multiply both sides of the equation by x
100=38.291605301915*x       - we divide both sides of the equation by (38.291605301915) to get x
100/38.291605301915=x
2.6115384615385=x
x=2.6115384615385

now we have:
20.37 is 2.6115384615385% of 780
