3.2 is what percent of 115 - 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 115 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 115, so we can write it down as 100%=115.
4. We know, that x% equals 3.2 of the output value, so we can write it down as x%=3.2.
5. Now we have two simple equations:
1) 100%=115
2) x%=3.2
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%=115/3.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.2 is what percent of 115

100%/x%=115/3.2
(100/x)*x=(115/3.2)*x       - we multiply both sides of the equation by x
100=35.9375*x       - we divide both sides of the equation by (35.9375) to get x
100/35.9375=x
2.7826086956522=x
x=2.7826086956522

now we have:
3.2 is 2.7826086956522% of 115
