499.99 is what percent of 899.99 - 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 899.99 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 899.99, so we can write it down as 100%=899.99.
4. We know, that x% equals 499.99 of the output value, so we can write it down as x%=499.99.
5. Now we have two simple equations:
1) 100%=899.99
2) x%=499.99
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%=899.99/499.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 499.99 is what percent of 899.99

100%/x%=899.99/499.99
(100/x)*x=(899.99/499.99)*x       - we multiply both sides of the equation by x
100=1.80001600032*x       - we divide both sides of the equation by (1.80001600032) to get x
100/1.80001600032=x
55.555061722908=x
x=55.555061722908

now we have:
499.99 is 55.555061722908% of 899.99
