891.15 is what percent of 1371 - 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 1371 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 1371, so we can write it down as 100%=1371.
4. We know, that x% equals 891.15 of the output value, so we can write it down as x%=891.15.
5. Now we have two simple equations:
1) 100%=1371
2) x%=891.15
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%=1371/891.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 891.15 is what percent of 1371

100%/x%=1371/891.15
(100/x)*x=(1371/891.15)*x       - we multiply both sides of the equation by x
100=1.5384615384615*x       - we divide both sides of the equation by (1.5384615384615) to get x
100/1.5384615384615=x
65=x
x=65

now we have:
891.15 is 65% of 1371
