61.8 is what percent of 82.4 - 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 82.4 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 82.4, so we can write it down as 100%=82.4.
4. We know, that x% equals 61.8 of the output value, so we can write it down as x%=61.8.
5. Now we have two simple equations:
1) 100%=82.4
2) x%=61.8
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%=82.4/61.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 61.8 is what percent of 82.4

100%/x%=82.4/61.8
(100/x)*x=(82.4/61.8)*x       - we multiply both sides of the equation by x
100=1.3333333333333*x       - we divide both sides of the equation by (1.3333333333333) to get x
100/1.3333333333333=x
75=x
x=75

now we have:
61.8 is 75% of 82.4
