342.88 is what percent of 520 - 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 520 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 520, so we can write it down as 100%=520.
4. We know, that x% equals 342.88 of the output value, so we can write it down as x%=342.88.
5. Now we have two simple equations:
1) 100%=520
2) x%=342.88
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%=520/342.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 342.88 is what percent of 520

100%/x%=520/342.88
(100/x)*x=(520/342.88)*x       - we multiply both sides of the equation by x
100=1.5165655622958*x       - we divide both sides of the equation by (1.5165655622958) to get x
100/1.5165655622958=x
65.938461538462=x
x=65.938461538462

now we have:
342.88 is 65.938461538462% of 520
