104.99 is what percent of 209.98 - 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 209.98 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 209.98, so we can write it down as 100%=209.98.
4. We know, that x% equals 104.99 of the output value, so we can write it down as x%=104.99.
5. Now we have two simple equations:
1) 100%=209.98
2) x%=104.99
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%=209.98/104.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 104.99 is what percent of 209.98

100%/x%=209.98/104.99
(100/x)*x=(209.98/104.99)*x       - we multiply both sides of the equation by x
100=2*x       - we divide both sides of the equation by (2) to get x
100/2=x
50=x
x=50

now we have:
104.99 is 50% of 209.98
