19.5 is what percent of 47.5 - 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 47.5 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 47.5, so we can write it down as 100%=47.5.
4. We know, that x% equals 19.5 of the output value, so we can write it down as x%=19.5.
5. Now we have two simple equations:
1) 100%=47.5
2) x%=19.5
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%=47.5/19.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.5 is what percent of 47.5

100%/x%=47.5/19.5
(100/x)*x=(47.5/19.5)*x       - we multiply both sides of the equation by x
100=2.4358974358974*x       - we divide both sides of the equation by (2.4358974358974) to get x
100/2.4358974358974=x
41.052631578947=x
x=41.052631578947

now we have:
19.5 is 41.052631578947% of 47.5
