3.7 is what percent of 13.15 - 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 13.15 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 13.15, so we can write it down as 100%=13.15.
4. We know, that x% equals 3.7 of the output value, so we can write it down as x%=3.7.
5. Now we have two simple equations:
1) 100%=13.15
2) x%=3.7
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%=13.15/3.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.7 is what percent of 13.15

100%/x%=13.15/3.7
(100/x)*x=(13.15/3.7)*x       - we multiply both sides of the equation by x
100=3.5540540540541*x       - we divide both sides of the equation by (3.5540540540541) to get x
100/3.5540540540541=x
28.136882129278=x
x=28.136882129278

now we have:
3.7 is 28.136882129278% of 13.15
