0.55 is what percent of 4.07 - 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 4.07 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 4.07, so we can write it down as 100%=4.07.
4. We know, that x% equals 0.55 of the output value, so we can write it down as x%=0.55.
5. Now we have two simple equations:
1) 100%=4.07
2) x%=0.55
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%=4.07/0.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.55 is what percent of 4.07

100%/x%=4.07/0.55
(100/x)*x=(4.07/0.55)*x       - we multiply both sides of the equation by x
100=7.4*x       - we divide both sides of the equation by (7.4) to get x
100/7.4=x
13.513513513514=x
x=13.513513513514

now we have:
0.55 is 13.513513513514% of 4.07
