1.5 is what percent of 40.8 - 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 40.8 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 40.8, so we can write it down as 100%=40.8.
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%=40.8
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%=40.8/1.5
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 40.8

100%/x%=40.8/1.5
(100/x)*x=(40.8/1.5)*x       - we multiply both sides of the equation by x
100=27.2*x       - we divide both sides of the equation by (27.2) to get x
100/27.2=x
3.6764705882353=x
x=3.6764705882353

now we have:
1.5 is 3.6764705882353% of 40.8
