1.8 is what percent of 37.5 - 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 37.5 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 37.5, so we can write it down as 100%=37.5.
4. We know, that x% equals 1.8 of the output value, so we can write it down as x%=1.8.
5. Now we have two simple equations:
1) 100%=37.5
2) x%=1.8
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%=37.5/1.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.8 is what percent of 37.5

100%/x%=37.5/1.8
(100/x)*x=(37.5/1.8)*x       - we multiply both sides of the equation by x
100=20.833333333333*x       - we divide both sides of the equation by (20.833333333333) to get x
100/20.833333333333=x
4.8=x
x=4.8

now we have:
1.8 is 4.8% of 37.5
