51 is what percent of 2150 - 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 2150 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 2150, so we can write it down as 100%=2150.
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%=2150
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%=2150/51
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 2150

100%/x%=2150/51
(100/x)*x=(2150/51)*x       - we multiply both sides of the equation by x
100=42.156862745098*x       - we divide both sides of the equation by (42.156862745098) to get x
100/42.156862745098=x
2.3720930232558=x
x=2.3720930232558

now we have:
51 is 2.3720930232558% of 2150
