0.3 is what percent of 54.45 - 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 54.45 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 54.45, so we can write it down as 100%=54.45.
4. We know, that x% equals 0.3 of the output value, so we can write it down as x%=0.3.
5. Now we have two simple equations:
1) 100%=54.45
2) x%=0.3
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%=54.45/0.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.3 is what percent of 54.45

100%/x%=54.45/0.3
(100/x)*x=(54.45/0.3)*x       - we multiply both sides of the equation by x
100=181.5*x       - we divide both sides of the equation by (181.5) to get x
100/181.5=x
0.55096418732782=x
x=0.55096418732782

now we have:
0.3 is 0.55096418732782% of 54.45
