55 is what percent of 299.5 - 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 299.5 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 299.5, so we can write it down as 100%=299.5.
4. We know, that x% equals 55 of the output value, so we can write it down as x%=55.
5. Now we have two simple equations:
1) 100%=299.5
2) x%=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%=299.5/55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55 is what percent of 299.5

100%/x%=299.5/55
(100/x)*x=(299.5/55)*x       - we multiply both sides of the equation by x
100=5.4454545454545*x       - we divide both sides of the equation by (5.4454545454545) to get x
100/5.4454545454545=x
18.363939899833=x
x=18.363939899833

now we have:
55 is 18.363939899833% of 299.5
