what fraction must be added to the difference of 5/6 and 2/3 to have an average of 1/4

Answer 1

5/6 - 4/6 = 1/6

1/6 + what = 2 (1/4)
twice because average of two things is sum over two

1/6 + what = 2/4 = 3/6

what = 2/6 = 1/3

Answer 2

the answer is not in the given choices
the choices are 35/2 , 40/2, 45/2

Answer 3

That does not make any sense to me.

Answer 4

i will try again on my own ,,anyway tnx for the ideas

Answer 5

How about this ?

(5/6 - 2/3 + x)/3 = 1/4
1/6 + x = 3/4
x = 3/4 - 1/6 = 7/12

I agree with Damon, the wording is rather ambiguous.
