It is hard to tell for sure, but one possibility is 2n-1/n
13/125/12 + 2/3= (5 + 8)/12= 13/12
21/3 is.
it is 15
5/6 is bigger than 2/3 (2/3 = 4/6, which is less than 5/6)
1 over3
The LCM of 2 and 3 is 6.
11/9
2(1/3)
2/1 divided by 11/3 is 0.5454 . . .
23.
11/3 - 2/3 = 4/3 - 2/3 = 2/3
2/3 x 10/31 = 20/93
It is hard to tell for sure, but one possibility is 2n-1/n
0.3333 repeating
It means equal fractoins. For example,2 over3 equals 4 over 6
13/125/12 + 2/3= (5 + 8)/12= 13/12
