10.8 is what percent of 11.9 - 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 11.9 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 11.9, so we can write it down as 100%=11.9.
4. We know, that x% equals 10.8 of the output value, so we can write it down as x%=10.8.
5. Now we have two simple equations:
1) 100%=11.9
2) x%=10.8
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%=11.9/10.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.8 is what percent of 11.9

100%/x%=11.9/10.8
(100/x)*x=(11.9/10.8)*x       - we multiply both sides of the equation by x
100=1.1018518518519*x       - we divide both sides of the equation by (1.1018518518519) to get x
100/1.1018518518519=x
90.756302521008=x
x=90.756302521008

now we have:
10.8 is 90.756302521008% of 11.9
