125.75 is what percent of 157.5 - 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 157.5 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 157.5, so we can write it down as 100%=157.5.
4. We know, that x% equals 125.75 of the output value, so we can write it down as x%=125.75.
5. Now we have two simple equations:
1) 100%=157.5
2) x%=125.75
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%=157.5/125.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 125.75 is what percent of 157.5

100%/x%=157.5/125.75
(100/x)*x=(157.5/125.75)*x       - we multiply both sides of the equation by x
100=1.2524850894632*x       - we divide both sides of the equation by (1.2524850894632) to get x
100/1.2524850894632=x
79.84126984127=x
x=79.84126984127

now we have:
125.75 is 79.84126984127% of 157.5
