61.5 is what percent of 69.5 - 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 69.5 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 100% equals 69.5, so we can write it down as 100%=69.5.
4. We know, that x% equals 61.5 of the output value, so we can write it down as x%=61.5.
5. Now we have two simple equations:
1) 100%=69.5
2) x%=61.5
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:
100%/x%=69.5/61.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 61.5 is what percent of 69.5

100%/x%=69.5/61.5
(100/x)*x=(69.5/61.5)*x       - we multiply both sides of the equation by x
100=1.130081300813*x       - we divide both sides of the equation by (1.130081300813) to get x
100/1.130081300813=x
88.489208633094=x
x=88.489208633094

now we have:
61.5 is 88.489208633094% of 69.5
