2.9 is what percent of 10.8 - 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 10.8 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 10.8, so we can write it down as 100%=10.8.
4. We know, that x% equals 2.9 of the output value, so we can write it down as x%=2.9.
5. Now we have two simple equations:
1) 100%=10.8
2) x%=2.9
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%=10.8/2.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.9 is what percent of 10.8

100%/x%=10.8/2.9
(100/x)*x=(10.8/2.9)*x       - we multiply both sides of the equation by x
100=3.7241379310345*x       - we divide both sides of the equation by (3.7241379310345) to get x
100/3.7241379310345=x
26.851851851852=x
x=26.851851851852

now we have:
2.9 is 26.851851851852% of 10.8
