  1. 3 · Three X's sit above 2/4, so three leaves measured 2/4 inch.
  2. True · Ana is right: range is longest minus shortest.
  3. 0.5 · 7/8 - 3/8 = 4/8 = 0.5 inch.
  4. One measurement at that value · Each X marks one item that measured exactly that length.
  5. 1 inch · 4 x 1/4 = 1 inch.
  6. 1.875 · 0.5 + 0.75 + 0.625 = 1.875 inches.
  7. 3/4 inch · 1 - 1/4 = 3/4 inch.
  8. 1/4 inch · Change 1/2 to 2/4, then subtract: 3/4 minus 2/4 equals 1/4 inch.
  9. 10/8 inch · Keep the denominator the same when you add: 5/8 + 5/8 = 10/8 inch, which is 1 and 2/8 inches.
  10. True · Zoe is right: 7/8 - 4/8 = 3/8.
