1138.78 is what percent of 2800 - 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 2800 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 2800, so we can write it down as 100%=2800.
4. We know, that x% equals 1138.78 of the output value, so we can write it down as x%=1138.78.
5. Now we have two simple equations:
1) 100%=2800
2) x%=1138.78
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%=2800/1138.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1138.78 is what percent of 2800

100%/x%=2800/1138.78
(100/x)*x=(2800/1138.78)*x       - we multiply both sides of the equation by x
100=2.4587716679253*x       - we divide both sides of the equation by (2.4587716679253) to get x
100/2.4587716679253=x
40.670714285714=x
x=40.670714285714

now we have:
1138.78 is 40.670714285714% of 2800
