2.42 is what percent of 19.5 - 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 19.5 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 19.5, so we can write it down as 100%=19.5.
4. We know, that x% equals 2.42 of the output value, so we can write it down as x%=2.42.
5. Now we have two simple equations:
1) 100%=19.5
2) x%=2.42
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%=19.5/2.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.42 is what percent of 19.5

100%/x%=19.5/2.42
(100/x)*x=(19.5/2.42)*x       - we multiply both sides of the equation by x
100=8.0578512396694*x       - we divide both sides of the equation by (8.0578512396694) to get x
100/8.0578512396694=x
12.410256410256=x
x=12.410256410256

now we have:
2.42 is 12.410256410256% of 19.5
