897.68 is what percent of 1015 - 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 1015 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 1015, so we can write it down as 100%=1015.
4. We know, that x% equals 897.68 of the output value, so we can write it down as x%=897.68.
5. Now we have two simple equations:
1) 100%=1015
2) x%=897.68
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%=1015/897.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 897.68 is what percent of 1015

100%/x%=1015/897.68
(100/x)*x=(1015/897.68)*x       - we multiply both sides of the equation by x
100=1.1306924516532*x       - we divide both sides of the equation by (1.1306924516532) to get x
100/1.1306924516532=x
88.441379310345=x
x=88.441379310345

now we have:
897.68 is 88.441379310345% of 1015
