781.88 is what percent of 1000 - 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 1000 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 1000, so we can write it down as 100%=1000.
4. We know, that x% equals 781.88 of the output value, so we can write it down as x%=781.88.
5. Now we have two simple equations:
1) 100%=1000
2) x%=781.88
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%=1000/781.88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 781.88 is what percent of 1000

100%/x%=1000/781.88
(100/x)*x=(1000/781.88)*x       - we multiply both sides of the equation by x
100=1.278968639689*x       - we divide both sides of the equation by (1.278968639689) to get x
100/1.278968639689=x
78.188=x
x=78.188

now we have:
781.88 is 78.188% of 1000
