31.25 is what percent of 42.68 - 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 42.68 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 42.68, so we can write it down as 100%=42.68.
4. We know, that x% equals 31.25 of the output value, so we can write it down as x%=31.25.
5. Now we have two simple equations:
1) 100%=42.68
2) x%=31.25
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%=42.68/31.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 31.25 is what percent of 42.68

100%/x%=42.68/31.25
(100/x)*x=(42.68/31.25)*x       - we multiply both sides of the equation by x
100=1.36576*x       - we divide both sides of the equation by (1.36576) to get x
100/1.36576=x
73.219306466729=x
x=73.219306466729

now we have:
31.25 is 73.219306466729% of 42.68
