812.5 is what percent of 1050 - 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 1050 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 1050, so we can write it down as 100%=1050.
4. We know, that x% equals 812.5 of the output value, so we can write it down as x%=812.5.
5. Now we have two simple equations:
1) 100%=1050
2) x%=812.5
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%=1050/812.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 812.5 is what percent of 1050

100%/x%=1050/812.5
(100/x)*x=(1050/812.5)*x       - we multiply both sides of the equation by x
100=1.2923076923077*x       - we divide both sides of the equation by (1.2923076923077) to get x
100/1.2923076923077=x
77.380952380952=x
x=77.380952380952

now we have:
812.5 is 77.380952380952% of 1050
