Q2. Millions.
Teaching note: Digit 7 is in the 7th place from right (ones, tens, hundreds, thousands, ten-thousands, hundred-thousands, millions).

Q3. 3 800 000.
Method: Look at hundred-thousands digit = 8, next digit (ten-thousands) = 4 (<5), so round down.
Common mistake: Rounding to 3 900 000 (wrong place).

Q4. 1, 2, 3, 4, 6, 9, 12, 18, 36.
Method: Pairs: 1×36, 2×18, 3×12, 4×9, 6×6.

Working: Spent = 1 875 + 2 340 = 4 215; Left = 5 400 − 4 215 = 1 185.
Marks: 1 (total spent), 1 (subtract), 1 (answer).

Q17. 675 000 packets.
Working: Shipped = 1 487 600 + 962 400 = 2 450 000; Remain = 3 125 000 − 2 450 000 = 675 000.
Marks: 1 (sum shipped), 1 (subtract), 1 (answer).

Q18. 33 800 books.
