39 is what percent of 2.6 - 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 2.6 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 2.6, so we can write it down as 100%=2.6.
4. We know, that x% equals 39 of the output value, so we can write it down as x%=39.
5. Now we have two simple equations:
1) 100%=2.6
2) x%=39
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%=2.6/39
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 39 is what percent of 2.6

100%/x%=2.6/39
(100/x)*x=(2.6/39)*x       - we multiply both sides of the equation by x
100=0.066666666666667*x       - we divide both sides of the equation by (0.066666666666667) to get x
100/0.066666666666667=x
1500=x
x=1500

now we have:
39 is 1500% of 2.6
