74 is what percent of 857 - 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 857 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 857, so we can write it down as 100%=857.
4. We know, that x% equals 74 of the output value, so we can write it down as x%=74.
5. Now we have two simple equations:
1) 100%=857
2) x%=74
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%=857/74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74 is what percent of 857

100%/x%=857/74
(100/x)*x=(857/74)*x       - we multiply both sides of the equation by x
100=11.581081081081*x       - we divide both sides of the equation by (11.581081081081) to get x
100/11.581081081081=x
8.634772462077=x
x=8.634772462077

now we have:
74 is 8.634772462077% of 857
