19.07 is what percent of 20.42 - 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 20.42 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 20.42, so we can write it down as 100%=20.42.
4. We know, that x% equals 19.07 of the output value, so we can write it down as x%=19.07.
5. Now we have two simple equations:
1) 100%=20.42
2) x%=19.07
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%=20.42/19.07
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.07 is what percent of 20.42

100%/x%=20.42/19.07
(100/x)*x=(20.42/19.07)*x       - we multiply both sides of the equation by x
100=1.070791819612*x       - we divide both sides of the equation by (1.070791819612) to get x
100/1.070791819612=x
93.388834476004=x
x=93.388834476004

now we have:
19.07 is 93.388834476004% of 20.42
