19.99 is what percent of 29 - 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 29 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 29, so we can write it down as 100%=29.
4. We know, that x% equals 19.99 of the output value, so we can write it down as x%=19.99.
5. Now we have two simple equations:
1) 100%=29
2) x%=19.99
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%=29/19.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.99 is what percent of 29

100%/x%=29/19.99
(100/x)*x=(29/19.99)*x       - we multiply both sides of the equation by x
100=1.4507253626813*x       - we divide both sides of the equation by (1.4507253626813) to get x
100/1.4507253626813=x
68.931034482759=x
x=68.931034482759

now we have:
19.99 is 68.931034482759% of 29
