30.5 is what percent of 45.2 - 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 45.2 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 45.2, so we can write it down as 100%=45.2.
4. We know, that x% equals 30.5 of the output value, so we can write it down as x%=30.5.
5. Now we have two simple equations:
1) 100%=45.2
2) x%=30.5
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%=45.2/30.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.5 is what percent of 45.2

100%/x%=45.2/30.5
(100/x)*x=(45.2/30.5)*x       - we multiply both sides of the equation by x
100=1.4819672131148*x       - we divide both sides of the equation by (1.4819672131148) to get x
100/1.4819672131148=x
67.477876106195=x
x=67.477876106195

now we have:
30.5 is 67.477876106195% of 45.2
