871.7 is what percent of 1263 - 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 1263 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 1263, so we can write it down as 100%=1263.
4. We know, that x% equals 871.7 of the output value, so we can write it down as x%=871.7.
5. Now we have two simple equations:
1) 100%=1263
2) x%=871.7
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%=1263/871.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 871.7 is what percent of 1263

100%/x%=1263/871.7
(100/x)*x=(1263/871.7)*x       - we multiply both sides of the equation by x
100=1.4488929677641*x       - we divide both sides of the equation by (1.4488929677641) to get x
100/1.4488929677641=x
69.01821060966=x
x=69.01821060966

now we have:
871.7 is 69.01821060966% of 1263
