2.7 is what percent of 8.6 - 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 8.6 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 8.6, so we can write it down as 100%=8.6.
4. We know, that x% equals 2.7 of the output value, so we can write it down as x%=2.7.
5. Now we have two simple equations:
1) 100%=8.6
2) x%=2.7
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%=8.6/2.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.7 is what percent of 8.6

100%/x%=8.6/2.7
(100/x)*x=(8.6/2.7)*x       - we multiply both sides of the equation by x
100=3.1851851851852*x       - we divide both sides of the equation by (3.1851851851852) to get x
100/3.1851851851852=x
31.395348837209=x
x=31.395348837209

now we have:
2.7 is 31.395348837209% of 8.6
