105.49 is what percent of 139 - 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 139 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 139, so we can write it down as 100%=139.
4. We know, that x% equals 105.49 of the output value, so we can write it down as x%=105.49.
5. Now we have two simple equations:
1) 100%=139
2) x%=105.49
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%=139/105.49
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 105.49 is what percent of 139

100%/x%=139/105.49
(100/x)*x=(139/105.49)*x       - we multiply both sides of the equation by x
100=1.317660441748*x       - we divide both sides of the equation by (1.317660441748) to get x
100/1.317660441748=x
75.892086330935=x
x=75.892086330935

now we have:
105.49 is 75.892086330935% of 139
