Method A: 7.6666.... = 7 + 0.6666... = 7 + 2/3 = 21/3 + 2/3 = 23/3
Method B: 10(7.666...) - 1(7.666...) = 76.666... - 7.666... = 69.000...
(10 - 1)(7.666...) = 69
7.666... = 69/9 = 23/3
Well I'm just doing some random math so it might be 300?
The answer is C. 8. Then both can have a denominator that looks like this..
6/8 and 5/8. Hope it helps!
