1) 4 2/5 +1/5 = D)4 3/5
2)5 6/9- 1/3 = 5 1/3 or 16/3
14. x - 1/5 = 4 2/5.....turn mixed number into improper fraction
      x - 1/5 = 22/5....add 1/5 to both sides
      x - 1/5 + 1/5 = 22/5 + 1/5 ...simplify
      x = 23/5 or 4 3/5

15. x + 1/3 = 5 6/9
      x + 1/3 = 51/9
     x = 51/9 - 1/3
      x = 51/9 - 3/9
      x = 48/9 or 5 1/3
