50.9 is what percent of 499 - 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 499 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 499, so we can write it down as 100%=499.
4. We know, that x% equals 50.9 of the output value, so we can write it down as x%=50.9.
5. Now we have two simple equations:
1) 100%=499
2) x%=50.9
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%=499/50.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 50.9 is what percent of 499

100%/x%=499/50.9
(100/x)*x=(499/50.9)*x       - we multiply both sides of the equation by x
100=9.803536345776*x       - we divide both sides of the equation by (9.803536345776) to get x
100/9.803536345776=x
10.200400801603=x
x=10.200400801603

now we have:
50.9 is 10.200400801603% of 499
