98.77 is what percent of 1291 - 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 1291 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 1291, so we can write it down as 100%=1291.
4. We know, that x% equals 98.77 of the output value, so we can write it down as x%=98.77.
5. Now we have two simple equations:
1) 100%=1291
2) x%=98.77
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%=1291/98.77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 98.77 is what percent of 1291

100%/x%=1291/98.77
(100/x)*x=(1291/98.77)*x       - we multiply both sides of the equation by x
100=13.070770476865*x       - we divide both sides of the equation by (13.070770476865) to get x
100/13.070770476865=x
7.6506584043377=x
x=7.6506584043377

now we have:
98.77 is 7.6506584043377% of 1291
