5.5 is what percent of 4.3 - 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 4.3 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 4.3, so we can write it down as 100%=4.3.
4. We know, that x% equals 5.5 of the output value, so we can write it down as x%=5.5.
5. Now we have two simple equations:
1) 100%=4.3
2) x%=5.5
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%=4.3/5.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.5 is what percent of 4.3

100%/x%=4.3/5.5
(100/x)*x=(4.3/5.5)*x       - we multiply both sides of the equation by x
100=0.78181818181818*x       - we divide both sides of the equation by (0.78181818181818) to get x
100/0.78181818181818=x
127.90697674419=x
x=127.90697674419

now we have:
5.5 is 127.90697674419% of 4.3
