1.5 is what percent of 39.9 - 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 39.9 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 39.9, so we can write it down as 100%=39.9.
4. We know, that x% equals 1.5 of the output value, so we can write it down as x%=1.5.
5. Now we have two simple equations:
1) 100%=39.9
2) x%=1.5
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%=39.9/1.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.5 is what percent of 39.9

100%/x%=39.9/1.5
(100/x)*x=(39.9/1.5)*x       - we multiply both sides of the equation by x
100=26.6*x       - we divide both sides of the equation by (26.6) to get x
100/26.6=x
3.7593984962406=x
x=3.7593984962406

now we have:
1.5 is 3.7593984962406% of 39.9
