19.95 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 19.95 of the output value, so we can write it down as x%=19.95.
5. Now we have two simple equations:
1) 100%=45
2) x%=19.95
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%=45/19.95
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.95 is what percent of 45

100%/x%=45/19.95
(100/x)*x=(45/19.95)*x       - we multiply both sides of the equation by x
100=2.2556390977444*x       - we divide both sides of the equation by (2.2556390977444) to get x
100/2.2556390977444=x
44.333333333333=x
x=44.333333333333

now we have:
19.95 is 44.333333333333% of 45
