  1. 4 · Five marks have four spaces between them: 0 to 1, 1 to 2, 2 to 3 and 3 to 4.
  2. 18 cm · The reading is 18 and the scale is marked cm. Record 18 cm.
  3. A 30 cm ruler · All three tools cover 15 cm. The 30 cm ruler is the shortest of them.
  4. True · Both reaches use inches. Since 60 is greater than 12, this tape covers a longer length in one placement.
  5. 4 · Each full placement is 1 metre. Four placements measure 4 metres.
  6. 6 · The book starts at zero and ends at 6 on the inch scale. Its width is 6 inches.
  7. The scale marked cm · cm means centimetres, so use the scale marked cm.
  8. False · The drooping tape follows a longer path. Hold it straight along the shelf before reading.
  9. Subtract the start: the length is 12 inches. · The first 2 inches on the scale lie before the table starts. Subtract them: 14 - 2 = 12 inches.
  10. 38 · Add all three parts: 15 + 15 + 8 = 38 cm.
