55.28 is what percent of 4.2 - 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 4.2 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 4.2, so we can write it down as 100%=4.2.
4. We know, that x% equals 55.28 of the output value, so we can write it down as x%=55.28.
5. Now we have two simple equations:
1) 100%=4.2
2) x%=55.28
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%=4.2/55.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55.28 is what percent of 4.2

100%/x%=4.2/55.28
(100/x)*x=(4.2/55.28)*x       - we multiply both sides of the equation by x
100=0.075976845151954*x       - we divide both sides of the equation by (0.075976845151954) to get x
100/0.075976845151954=x
1316.1904761905=x
x=1316.1904761905

now we have:
55.28 is 1316.1904761905% of 4.2
