19.6 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 19.6 of the output value, so we can write it down as x%=19.6.
5. Now we have two simple equations:
1) 100%=40.8
2) x%=19.6
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%=40.8/19.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.6 is what percent of 40.8

100%/x%=40.8/19.6
(100/x)*x=(40.8/19.6)*x       - we multiply both sides of the equation by x
100=2.0816326530612*x       - we divide both sides of the equation by (2.0816326530612) to get x
100/2.0816326530612=x
48.039215686275=x
x=48.039215686275

now we have:
19.6 is 48.039215686275% of 40.8
