  1. 1/3 + 1/3 = 2/3
  2. 3/4 − 1/4 = 2/4
  3. 11/12 + 3/12 = 13/12 or 11/12
  4. 9/5 − 3/5 = 6/5 or 11/5
  5. 6/8 − n = 1/8, n = 5/8
  6. n + 1/4 = 3/4; n = 2/4
  7. 5/4 + 3/4 = 8/4 or 2
  8. 11/3 + 2/3 = 4/3 + 2/3 = 6/3 or 2
  9. Possible response: I used my fraction strip to show 6/8. Then I folded back all but 1/8. I saw that I folded back 5/8,
    so n = 5/8.
