70 is what percent of 624 - 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 624 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 624, so we can write it down as 100%=624.
4. We know, that x% equals 70 of the output value, so we can write it down as x%=70.
5. Now we have two simple equations:
1) 100%=624
2) x%=70
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%=624/70
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 70 is what percent of 624

100%/x%=624/70
(100/x)*x=(624/70)*x       - we multiply both sides of the equation by x
100=8.9142857142857*x       - we divide both sides of the equation by (8.9142857142857) to get x
100/8.9142857142857=x
11.217948717949=x
x=11.217948717949

now we have:
70 is 11.217948717949% of 624
