78.24 is what percent of 662 - 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 662 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 662, so we can write it down as 100%=662.
4. We know, that x% equals 78.24 of the output value, so we can write it down as x%=78.24.
5. Now we have two simple equations:
1) 100%=662
2) x%=78.24
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%=662/78.24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 78.24 is what percent of 662

100%/x%=662/78.24
(100/x)*x=(662/78.24)*x       - we multiply both sides of the equation by x
100=8.461145194274*x       - we divide both sides of the equation by (8.461145194274) to get x
100/8.461145194274=x
11.818731117825=x
x=11.818731117825

now we have:
78.24 is 11.818731117825% of 662
