10.9 is what percent of 4.75 - 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 4.75 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 4.75, so we can write it down as 100%=4.75.
4. We know, that x% equals 10.9 of the output value, so we can write it down as x%=10.9.
5. Now we have two simple equations:
1) 100%=4.75
2) x%=10.9
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%=4.75/10.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 10.9 is what percent of 4.75

100%/x%=4.75/10.9
(100/x)*x=(4.75/10.9)*x       - we multiply both sides of the equation by x
100=0.43577981651376*x       - we divide both sides of the equation by (0.43577981651376) to get x
100/0.43577981651376=x
229.47368421053=x
x=229.47368421053

now we have:
10.9 is 229.47368421053% of 4.75
