7942.82 is what percent of 10100.4 - 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 10100.4 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 10100.4, so we can write it down as 100%=10100.4.
4. We know, that x% equals 7942.82 of the output value, so we can write it down as x%=7942.82.
5. Now we have two simple equations:
1) 100%=10100.4
2) x%=7942.82
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%=10100.4/7942.82
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7942.82 is what percent of 10100.4

100%/x%=10100.4/7942.82
(100/x)*x=(10100.4/7942.82)*x       - we multiply both sides of the equation by x
100=1.2716390400387*x       - we divide both sides of the equation by (1.2716390400387) to get x
100/1.2716390400387=x
78.638667775534=x
x=78.638667775534

now we have:
7942.82 is 78.638667775534% of 10100.4
