What is 77.5 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 77.5% of the output value, so we can write it down as x=77.5%.
5. Now we have two simple equations:
1) 97.5=100%
2) x=77.5%
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%/77.5%
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 77.5% of 97.5

97.5/x=100/77.5
(97.5/x)*x=(100/77.5)*x       - we multiply both sides of the equation by x
97.5=1.2903225806452*x       - we divide both sides of the equation by (1.2903225806452) to get x
97.5/1.2903225806452=x
75.5625=x
x=75.5625

now we have:
77.5% of 97.5=75.5625
