51 is what percent of 6918 - 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 6918 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 6918, so we can write it down as 100%=6918.
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%=6918
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%=6918/51
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 6918

100%/x%=6918/51
(100/x)*x=(6918/51)*x       - we multiply both sides of the equation by x
100=135.64705882353*x       - we divide both sides of the equation by (135.64705882353) to get x
100/135.64705882353=x
0.73720728534258=x
x=0.73720728534258

now we have:
51 is 0.73720728534258% of 6918
