2.7 is what percent of 5.7 - 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 5.7 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 5.7, so we can write it down as 100%=5.7.
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%=5.7
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%=5.7/2.7
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 5.7

100%/x%=5.7/2.7
(100/x)*x=(5.7/2.7)*x       - we multiply both sides of the equation by x
100=2.1111111111111*x       - we divide both sides of the equation by (2.1111111111111) to get x
100/2.1111111111111=x
47.368421052632=x
x=47.368421052632

now we have:
2.7 is 47.368421052632% of 5.7
