Chapter 9, Coconut Farm, connects multiplication and division as inverse operations and introduces division with a remainder. These questions use coconut-packing situations to make both ideas concrete.
Practice Questions
Q1. A farmer packs 96 coconuts into bags of 8. How many bags are needed?
96 ÷ 8 = 12 bags.
Q2. Check the answer to Q1 using multiplication.
12 × 8 = 96, which matches — confirming that multiplication and division undo each other.
Q3. 53 coconuts are packed into bags of 6. How many full bags are made, and how many coconuts are left over?
53 ÷ 6 = 8 remainder 5, so 8 full bags are made with 5 coconuts left over.
Q4. A tree gives 7 coconuts a month. How many in 9 months? Check your answer by dividing it by 9.
7 × 9 = 63 coconuts; 63 ÷ 9 = 7, which checks out.
Q5. A farmer has 100 coconuts and sells them in packs of 9. How many packs can be made, and how many coconuts remain?
100 ÷ 9 = 11 remainder 1, so 11 packs are made with 1 coconut left over.
Why These Help
Packing, sharing and grouping objects is exactly what division models in real life, and seeing the leftover items as a genuine “remainder” (rather than an error) prepares students for fractions and later work with exact versus approximate answers.
Frequently Asked Questions
Q. Why do multiplication and division “undo” each other?
Because division splits a total into equal groups, while multiplication combines equal groups back into that same total — each operation reverses the other.
