30.5 is what percent of 101.15 - 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 101.15 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 101.15, so we can write it down as 100%=101.15.
4. We know, that x% equals 30.5 of the output value, so we can write it down as x%=30.5.
5. Now we have two simple equations:
1) 100%=101.15
2) x%=30.5
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%=101.15/30.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.5 is what percent of 101.15

100%/x%=101.15/30.5
(100/x)*x=(101.15/30.5)*x       - we multiply both sides of the equation by x
100=3.316393442623*x       - we divide both sides of the equation by (3.316393442623) to get x
100/3.316393442623=x
30.153237765695=x
x=30.153237765695

now we have:
30.5 is 30.153237765695% of 101.15
