15.7 is what percent of 17 - 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 17 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 17, so we can write it down as 100%=17.
4. We know, that x% equals 15.7 of the output value, so we can write it down as x%=15.7.
5. Now we have two simple equations:
1) 100%=17
2) x%=15.7
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%=17/15.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.7 is what percent of 17

100%/x%=17/15.7
(100/x)*x=(17/15.7)*x       - we multiply both sides of the equation by x
100=1.0828025477707*x       - we divide both sides of the equation by (1.0828025477707) to get x
100/1.0828025477707=x
92.352941176471=x
x=92.352941176471

now we have:
15.7 is 92.352941176471% of 17
