177.5 is what percent of 505 - 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 505 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 505, so we can write it down as 100%=505.
4. We know, that x% equals 177.5 of the output value, so we can write it down as x%=177.5.
5. Now we have two simple equations:
1) 100%=505
2) x%=177.5
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%=505/177.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 177.5 is what percent of 505

100%/x%=505/177.5
(100/x)*x=(505/177.5)*x       - we multiply both sides of the equation by x
100=2.8450704225352*x       - we divide both sides of the equation by (2.8450704225352) to get x
100/2.8450704225352=x
35.148514851485=x
x=35.148514851485

now we have:
177.5 is 35.148514851485% of 505
