19.45 is what percent of 83 - 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 83 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 83, so we can write it down as 100%=83.
4. We know, that x% equals 19.45 of the output value, so we can write it down as x%=19.45.
5. Now we have two simple equations:
1) 100%=83
2) x%=19.45
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%=83/19.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.45 is what percent of 83

100%/x%=83/19.45
(100/x)*x=(83/19.45)*x       - we multiply both sides of the equation by x
100=4.26735218509*x       - we divide both sides of the equation by (4.26735218509) to get x
100/4.26735218509=x
23.433734939759=x
x=23.433734939759

now we have:
19.45 is 23.433734939759% of 83
