105.9 is what percent of 124.4 - 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 124.4 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 124.4, so we can write it down as 100%=124.4.
4. We know, that x% equals 105.9 of the output value, so we can write it down as x%=105.9.
5. Now we have two simple equations:
1) 100%=124.4
2) x%=105.9
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%=124.4/105.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 105.9 is what percent of 124.4

100%/x%=124.4/105.9
(100/x)*x=(124.4/105.9)*x       - we multiply both sides of the equation by x
100=1.1746931067044*x       - we divide both sides of the equation by (1.1746931067044) to get x
100/1.1746931067044=x
85.128617363344=x
x=85.128617363344

now we have:
105.9 is 85.128617363344% of 124.4
