19.83 is what percent of 45 - 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 45 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 45, so we can write it down as 100%=45.
4. We know, that x% equals 19.83 of the output value, so we can write it down as x%=19.83.
5. Now we have two simple equations:
1) 100%=45
2) x%=19.83
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%=45/19.83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.83 is what percent of 45

100%/x%=45/19.83
(100/x)*x=(45/19.83)*x       - we multiply both sides of the equation by x
100=2.2692889561271*x       - we divide both sides of the equation by (2.2692889561271) to get x
100/2.2692889561271=x
44.066666666667=x
x=44.066666666667

now we have:
19.83 is 44.066666666667% of 45
