Answer:94%
Step-by-step explanation:
1. We assume, that the number 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 9, so we can write it down as 100%=9.
4. We know, that x% equals 8.46 of the output value, so we can write it down as x%=8.46.
5. Now we have two simple equations:
1) 100%=9
2) x%=8.46
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%=9/8.46
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 8.46 is what percent of 9
100%/x%=9/8.46
(100/x)*x=(9/8.46)*x - we multiply both sides of the equation by x
100=1.063829787234*x - we divide both sides of the equation by (1.063829787234) to get x
100/1.063829787234=x
94=x
x=94
now we have:
8.46 is 94% of 9
