55.3 is what percent of 263.3 - 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 263.3 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 263.3, so we can write it down as 100%=263.3.
4. We know, that x% equals 55.3 of the output value, so we can write it down as x%=55.3.
5. Now we have two simple equations:
1) 100%=263.3
2) x%=55.3
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%=263.3/55.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55.3 is what percent of 263.3

100%/x%=263.3/55.3
(100/x)*x=(263.3/55.3)*x       - we multiply both sides of the equation by x
100=4.7613019891501*x       - we divide both sides of the equation by (4.7613019891501) to get x
100/4.7613019891501=x
21.002658564375=x
x=21.002658564375

now we have:
55.3 is 21.002658564375% of 263.3
