1.52 is what percent of 3.8 - 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 3.8 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 3.8, so we can write it down as 100%=3.8.
4. We know, that x% equals 1.52 of the output value, so we can write it down as x%=1.52.
5. Now we have two simple equations:
1) 100%=3.8
2) x%=1.52
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%=3.8/1.52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.52 is what percent of 3.8

100%/x%=3.8/1.52
(100/x)*x=(3.8/1.52)*x       - we multiply both sides of the equation by x
100=2.5*x       - we divide both sides of the equation by (2.5) to get x
100/2.5=x
40=x
x=40

now we have:
1.52 is 40% of 3.8
