65 is what percent of 129.99 - 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 129.99 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 129.99, so we can write it down as 100%=129.99.
4. We know, that x% equals 65 of the output value, so we can write it down as x%=65.
5. Now we have two simple equations:
1) 100%=129.99
2) x%=65
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%=129.99/65
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 65 is what percent of 129.99

100%/x%=129.99/65
(100/x)*x=(129.99/65)*x       - we multiply both sides of the equation by x
100=1.9998461538462*x       - we divide both sides of the equation by (1.9998461538462) to get x
100/1.9998461538462=x
50.003846449727=x
x=50.003846449727

now we have:
65 is 50.003846449727% of 129.99
