8.75 is what percent of 31.9 - 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 31.9 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 31.9, so we can write it down as 100%=31.9.
4. We know, that x% equals 8.75 of the output value, so we can write it down as x%=8.75.
5. Now we have two simple equations:
1) 100%=31.9
2) x%=8.75
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%=31.9/8.75
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 8.75 is what percent of 31.9

100%/x%=31.9/8.75
(100/x)*x=(31.9/8.75)*x       - we multiply both sides of the equation by x
100=3.6457142857143*x       - we divide both sides of the equation by (3.6457142857143) to get x
100/3.6457142857143=x
27.42946708464=x
x=27.42946708464

now we have:
8.75 is 27.42946708464% of 31.9
