51 is what percent of 2198 - 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 2198 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 2198, so we can write it down as 100%=2198.
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%=2198
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%=2198/51
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 2198

100%/x%=2198/51
(100/x)*x=(2198/51)*x       - we multiply both sides of the equation by x
100=43.098039215686*x       - we divide both sides of the equation by (43.098039215686) to get x
100/43.098039215686=x
2.3202911737944=x
x=2.3202911737944

now we have:
51 is 2.3202911737944% of 2198
