9.99 is what percent of 0.75 - 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 0.75 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 0.75, so we can write it down as 100%=0.75.
4. We know, that x% equals 9.99 of the output value, so we can write it down as x%=9.99.
5. Now we have two simple equations:
1) 100%=0.75
2) x%=9.99
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%=0.75/9.99
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.99 is what percent of 0.75

100%/x%=0.75/9.99
(100/x)*x=(0.75/9.99)*x       - we multiply both sides of the equation by x
100=0.075075075075075*x       - we divide both sides of the equation by (0.075075075075075) to get x
100/0.075075075075075=x
1332=x
x=1332

now we have:
9.99 is 1332% of 0.75
