147.5 is what percent of 172.5 - 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 172.5 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 172.5, so we can write it down as 100%=172.5.
4. We know, that x% equals 147.5 of the output value, so we can write it down as x%=147.5.
5. Now we have two simple equations:
1) 100%=172.5
2) x%=147.5
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%=172.5/147.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 147.5 is what percent of 172.5

100%/x%=172.5/147.5
(100/x)*x=(172.5/147.5)*x       - we multiply both sides of the equation by x
100=1.1694915254237*x       - we divide both sides of the equation by (1.1694915254237) to get x
100/1.1694915254237=x
85.507246376812=x
x=85.507246376812

now we have:
147.5 is 85.507246376812% of 172.5
