    Weighted mean \[\frac{3\times 2.2+1\times 8.5}{4}\]

    I don't think the correct way to find the answer is using the 6.3. All of the possible answers you are giving me are not options. Its just like your walking from point a to point b in this case its 2.2 and 8.5. What Point are you at when you stop one-fourth of the way? Could that work?

    take 1/4th of 6.3 then add that result to 2.2

    taking 1/4th of 6.3 is the same as dividing 6.3 over 4 when you used that calculator, what is the result of 6.3/4 ?

    If you add 2.2 to that. Then my answer was correct.

    1/4 distance from a to b \[a+\frac{b-a}{4}=\frac{4a}{4}+\frac{b-a}{4}=\frac{4a+b-a}{4}=\frac{3a+b}{4}\] so you can just use a weighted mean. \[\frac{3\times2.2+8.5}{4}=3.775\]
