What is 91.5 percent of 97.5 - 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 97.5 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 97.5 is 100%, so we can write it down as 97.5=100%.
4. We know, that x is 91.5% of the output value, so we can write it down as x=91.5%.
5. Now we have two simple equations:
1) 97.5=100%
2) x=91.5%
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:
97.5/x=100%/91.5%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 91.5% of 97.5

97.5/x=100/91.5
(97.5/x)*x=(100/91.5)*x       - we multiply both sides of the equation by x
97.5=1.0928961748634*x       - we divide both sides of the equation by (1.0928961748634) to get x
97.5/1.0928961748634=x
89.2125=x
x=89.2125

now we have:
91.5% of 97.5=89.2125
