27 is what percent of 31.59 - 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 31.59 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 31.59, so we can write it down as 100%=31.59.
4. We know, that x% equals 27 of the output value, so we can write it down as x%=27.
5. Now we have two simple equations:
1) 100%=31.59
2) x%=27
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%=31.59/27
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27 is what percent of 31.59

100%/x%=31.59/27
(100/x)*x=(31.59/27)*x       - we multiply both sides of the equation by x
100=1.17*x       - we divide both sides of the equation by (1.17) to get x
100/1.17=x
85.470085470085=x
x=85.470085470085

now we have:
27 is 85.470085470085% of 31.59
