1. We assume, that the number 36 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 36, so we can write it down as 100%=36. 4. We know, that x% equals 19.8 of the output value, so we can write it down as x%=19.8. 5. Now we have two simple equations: 1) 100%=36 2) x%=19.8 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%=36/19.8 6. Now we just have to solve the simple equation, and we will get the solution we are looking for. 7. Solution: 19.8 is 55% of 36
