0.45 is what percent of 3.48 - 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 3.48 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 3.48, so we can write it down as 100%=3.48.
4. We know, that x% equals 0.45 of the output value, so we can write it down as x%=0.45.
5. Now we have two simple equations:
1) 100%=3.48
2) x%=0.45
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%=3.48/0.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.45 is what percent of 3.48

100%/x%=3.48/0.45
(100/x)*x=(3.48/0.45)*x       - we multiply both sides of the equation by x
100=7.7333333333333*x       - we divide both sides of the equation by (7.7333333333333) to get x
100/7.7333333333333=x
12.931034482759=x
x=12.931034482759

now we have:
0.45 is 12.931034482759% of 3.48
