51 is what percent of 940 - 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 940 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 940, so we can write it down as 100%=940.
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%=940
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%=940/51
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 940

100%/x%=940/51
(100/x)*x=(940/51)*x       - we multiply both sides of the equation by x
100=18.43137254902*x       - we divide both sides of the equation by (18.43137254902) to get x
100/18.43137254902=x
5.4255319148936=x
x=5.4255319148936

now we have:
51 is 5.4255319148936% of 940
