No, 4/12 is the same as 4 divided by 12 which is 1/3 or .33333333, while 1/2 is the same as 1 divided by 2 which is .5, as you can see .5 is bigger than .33333333 so 1/2 is bigger than 4/12
6 1/2 divided by 5 = 13/2 (1/5) = 13/10 or 1 3/10

2 3/5 ÷ 5 = (2×5+3)/5 ÷ 5/1 = 13/5 ÷ 5/1 = 13/5 × 1/5 = (13×1)/(5×5) = 13/25
(2/3)/(5/13)=(2/3)*(13/5)=26/15

5/13 ÷ 15/26 = 2/3
4/5 ÷ 1/2 = 8/5 or 13/5
(5/6) / (13/12) = (5/6) x (12/13) = (5/1) x (2/13) = 10/13
