868.75 is what percent of 139 - 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 139 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 139, so we can write it down as 100%=139.
4. We know, that x% equals 868.75 of the output value, so we can write it down as x%=868.75.
5. Now we have two simple equations:
1) 100%=139
2) x%=868.75
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%=139/868.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 868.75 is what percent of 139

100%/x%=139/868.75
(100/x)*x=(139/868.75)*x       - we multiply both sides of the equation by x
100=0.16*x       - we divide both sides of the equation by (0.16) to get x
100/0.16=x
625=x
x=625

now we have:
868.75 is 625% of 139
