13/125/12 + 2/3= (5 + 8)/12= 13/12
It is hard to tell for sure, but one possibility is 2n-1/n
They add up to 25/6 and (25/6)/9 = 25/54 which is the mean
1/8 plus 1/4 plus 1/2 = 7/8 or 0.875
4 over 8 is the same as 1 over 2, so 1 over 2 plus 1 over 2 (.5+.5 OR 1/2 +1/2) is 1. The answer is 1.

1/10 + 5/6 + 2/3 = 3/30 + 25/30 + 20/30 = 48/30 = 16/10 or 13/5
2/1 divided by 11/3 is 0.5454 . . .
2/3 + 1/6 + 1/6 multiply the 2/3 by 2/2 to get a common denominator 4/6 + 1/6 + 1/6 add the numerators (4+1+1)/6 6/6 6/6 = 1
1 over 1 2 over 2 3 over3 1,000,000 over 1,000,000 any fraction if they have the same numerator and denominator.
13/125/12 + 2/3= (5 + 8)/12= 13/12
2/3 x 10/31 = 20/93
It is hard to tell for sure, but one possibility is 2n-1/n
2(1/3)
1 over 2 plus 1 over 2= 2 over 2= 1 whole
They add up to 25/6 and (25/6)/9 = 25/54 which is the mean
