61.3 is what percent of 78 - 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 78 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 78, so we can write it down as 100%=78.
4. We know, that x% equals 61.3 of the output value, so we can write it down as x%=61.3.
5. Now we have two simple equations:
1) 100%=78
2) x%=61.3
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%=78/61.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 61.3 is what percent of 78

100%/x%=78/61.3
(100/x)*x=(78/61.3)*x       - we multiply both sides of the equation by x
100=1.2724306688418*x       - we divide both sides of the equation by (1.2724306688418) to get x
100/1.2724306688418=x
78.589743589744=x
x=78.589743589744

now we have:
61.3 is 78.589743589744% of 78
