4.5 is what percent of 33.91 - 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 33.91 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 33.91, so we can write it down as 100%=33.91.
4. We know, that x% equals 4.5 of the output value, so we can write it down as x%=4.5.
5. Now we have two simple equations:
1) 100%=33.91
2) x%=4.5
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%=33.91/4.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.5 is what percent of 33.91

100%/x%=33.91/4.5
(100/x)*x=(33.91/4.5)*x       - we multiply both sides of the equation by x
100=7.5355555555556*x       - we divide both sides of the equation by (7.5355555555556) to get x
100/7.5355555555556=x
13.270421704512=x
x=13.270421704512

now we have:
4.5 is 13.270421704512% of 33.91
