999.99 is what percent of 1500 - 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 1500 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 1500, so we can write it down as 100%=1500.
4. We know, that x% equals 999.99 of the output value, so we can write it down as x%=999.99.
5. Now we have two simple equations:
1) 100%=1500
2) x%=999.99
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%=1500/999.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 999.99 is what percent of 1500

100%/x%=1500/999.99
(100/x)*x=(1500/999.99)*x       - we multiply both sides of the equation by x
100=1.50001500015*x       - we divide both sides of the equation by (1.50001500015) to get x
100/1.50001500015=x
66.666=x
x=66.666

now we have:
999.99 is 66.666% of 1500
