49 is what percent of 9.1 - 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 9.1 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 9.1, so we can write it down as 100%=9.1.
4. We know, that x% equals 49 of the output value, so we can write it down as x%=49.
5. Now we have two simple equations:
1) 100%=9.1
2) x%=49
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%=9.1/49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 49 is what percent of 9.1

100%/x%=9.1/49
(100/x)*x=(9.1/49)*x       - we multiply both sides of the equation by x
100=0.18571428571429*x       - we divide both sides of the equation by (0.18571428571429) to get x
100/0.18571428571429=x
538.46153846154=x
x=538.46153846154

now we have:
49 is 538.46153846154% of 9.1
