19.95 is what percent of 12.7 - 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 12.7 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 12.7, so we can write it down as 100%=12.7.
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%=12.7
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%=12.7/19.95
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 12.7

100%/x%=12.7/19.95
(100/x)*x=(12.7/19.95)*x       - we multiply both sides of the equation by x
100=0.63659147869674*x       - we divide both sides of the equation by (0.63659147869674) to get x
100/0.63659147869674=x
157.08661417323=x
x=157.08661417323

now we have:
19.95 is 157.08661417323% of 12.7
