In number form, your question is: 14 5/9 + 6 7/9 = ? We can now understand this easier, and answer it. Add your whole numbers first to not get confused. 14 + 6 = 20. Now add your fractions. 5/9 + 7/9 = 12/9, = 1 3/9. Add 1 to your whole number. 20 + 1 = 21. You are left with 21 3/9. Your answer is 21 3/9. I hope this helps!
It is the first one because it you mark the number 2 between 0 and 4 and the number 5 between 0 and 10, you can see it is just in the middle which is 2:5
