9.6 is what percent of 18.9 - 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 18.9 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 18.9, so we can write it down as 100%=18.9.
4. We know, that x% equals 9.6 of the output value, so we can write it down as x%=9.6.
5. Now we have two simple equations:
1) 100%=18.9
2) x%=9.6
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%=18.9/9.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.6 is what percent of 18.9

100%/x%=18.9/9.6
(100/x)*x=(18.9/9.6)*x       - we multiply both sides of the equation by x
100=1.96875*x       - we divide both sides of the equation by (1.96875) to get x
100/1.96875=x
50.793650793651=x
x=50.793650793651

now we have:
9.6 is 50.793650793651% of 18.9
