42.3 is what percent of 9.4 - 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 9.4 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 9.4, so we can write it down as 100%=9.4.
4. We know, that x% equals 42.3 of the output value, so we can write it down as x%=42.3.
5. Now we have two simple equations:
1) 100%=9.4
2) x%=42.3
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%=9.4/42.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.3 is what percent of 9.4

100%/x%=9.4/42.3
(100/x)*x=(9.4/42.3)*x       - we multiply both sides of the equation by x
100=0.22222222222222*x       - we divide both sides of the equation by (0.22222222222222) to get x
100/0.22222222222222=x
450=x
x=450

now we have:
42.3 is 450% of 9.4
