311.02 is what percent of 9900 - 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 9900 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 9900, so we can write it down as 100%=9900.
4. We know, that x% equals 311.02 of the output value, so we can write it down as x%=311.02.
5. Now we have two simple equations:
1) 100%=9900
2) x%=311.02
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%=9900/311.02
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 311.02 is what percent of 9900

100%/x%=9900/311.02
(100/x)*x=(9900/311.02)*x       - we multiply both sides of the equation by x
100=31.830750434056*x       - we divide both sides of the equation by (31.830750434056) to get x
100/31.830750434056=x
3.1416161616162=x
x=3.1416161616162

now we have:
311.02 is 3.1416161616162% of 9900
