  1. 4 · 4 quarters fill an inch because 4 lots of 1/4 make 1 whole.
  2. 5 and 1/4 inches · 5 and 1/4 inches is correct because the first quarter mark past 5 adds one quarter.
  3. 3/4 · Three of the four equal quarters are shaded, so the length is 3/4 inch.
  4. Vrai · Every X is one measurement. Two X's above the same mark mean two objects had that same length.
  5. 5 · 5 pencils because 2 + 3 = 5 Xs and each X is one pencil.
  6. 4 1/4 inches · Each quarter-mark adds 1/4 inch, so one quarter past 4 inches is 4 1/4 inches.
  7. 6 and 1/2 inches · 6 and 1/2 inches is correct because halfway is one half past 6.
  8. Vrai · Dan is right because the third quarter mark past 2 is 2 and 3/4.
  9. He used the wrong mark · 2 3/4 inches is closest to the 2 3/4 mark, not the 3-inch mark, so Jake's X belongs one mark to the left.
  10. 5 · 5 pencils because 2 + 2 + 1 = 5.
