51 is what percent of 560 - 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 560 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 560, so we can write it down as 100%=560.
4. We know, that x% equals 51 of the output value, so we can write it down as x%=51.
5. Now we have two simple equations:
1) 100%=560
2) x%=51
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%=560/51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51 is what percent of 560

100%/x%=560/51
(100/x)*x=(560/51)*x       - we multiply both sides of the equation by x
100=10.980392156863*x       - we divide both sides of the equation by (10.980392156863) to get x
100/10.980392156863=x
9.1071428571429=x
x=9.1071428571429

now we have:
51 is 9.1071428571429% of 560
