8/8 - (2/8 + 1/8 + 4/8) = ?
(1/4) 16 = 4 lettuce

(1/8) 16 = 2 punpkin

(1/2) 16 = 8 red tulips

4+2+8 = 14

16-14 = 2 rows of carrots
To solve this problem, I would convert the fractions to the same denominater.
1/4= 4/16
1/2= 8/16
1/8= 2/16

Now you add the fractions all together and you get 14/16. So I think 2 of the rows are carrots.
