2.97 is what percent of 5.4 - 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 5.4 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 5.4, so we can write it down as 100%=5.4.
4. We know, that x% equals 2.97 of the output value, so we can write it down as x%=2.97.
5. Now we have two simple equations:
1) 100%=5.4
2) x%=2.97
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%=5.4/2.97
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.97 is what percent of 5.4

100%/x%=5.4/2.97
(100/x)*x=(5.4/2.97)*x       - we multiply both sides of the equation by x
100=1.8181818181818*x       - we divide both sides of the equation by (1.8181818181818) to get x
100/1.8181818181818=x
55=x
x=55

now we have:
2.97 is 55% of 5.4
