NCERT Solutions for Class 5th Maths Chapter 9 Coconut Farm

About this chapter
Division is sharing into equal groups. Look at 35 coconuts set out in 5 rows of 7. Split them into 7 groups and each group has 5. Split them into 5 groups and each group has 7. So one multiplication fact, 5 × 7 = 35, gives two division facts: 35 ÷ 7 = 5 and 35 ÷ 5 = 7. The three names. In 35 ÷ 5 = 7, the number being shared (35) is the dividend , written N. The number of groups (5) is the divisor , written D. The answer (7) is the quotient , written Q. The book's rule is N = D × Q . You can always check a division by multiplying back. Zeros make division easy. If you know 15 × 6 = 90, then you also know 150 × 6 = 900, so 900 ÷ 6 = 150 and 900 ÷ 150 = 6. Dividing 4000 by 10 just moves every digit one place to the right: 4000 ÷ 10 = 400. That is why 40 ÷ 10 = 4, 400 ÷ 10 = 40 and 4000 ÷ 10 =

Quick revision
| Word | What it means | Where it appears | Example |
|---|---|---|---|
| Array | Things set out in equal rows and columns | Page 119, the coconuts | 5 rows of 7 coconuts = 35 |
| Multiplication fact | A true sentence using × | Page 119 | 5 × 7 = 35 |
| Division fact | A true sentence using ÷ that comes from a multiplication fact | Division Facts box, page 119 | 35 ÷ 5 = 7 |
| Dividend (N) | The number being shared out | Notice! box, page 119 | In 35 ÷ 5 = 7, N is 35 |
| Divisor (D) | The number you are sharing by | Notice! box, page 119 | In 35 ÷ 5 = 7, D is 5 |
| Quotient (Q) | The answer of a division | Notice! box, page 119 | In 35 ÷ 5 = 7, Q is 7 |
| Remainder (R) | What is left over when the sharing is not even | Page 125 | 535 ÷ 25 leaves R = 10 |
| N = D × Q + R | The rule that ties all four together | Pink box, page 125 | 535 = 25 × 21 + 10 |
| Splitting the number | Breaking the dividend into easy parts before dividing | Mental Strategies for Division, page 123 | 1248 = 1200 + 48 |
| Repeated halving | Halving again and again to divide by 2, 4, 8 … | Page 123 | 128 → 64 → 32, so 128 ÷ 4 = 32 |
| Partial quotients | Taking away big chunks of the divisor and adding up the chunks | Susie's Farm in Kerala, page 124 | 582 ÷ 6 = 90 + 7 |
| Division using place value | Dividing the Thousands, then Hundreds, then Tens, then Ones | Page 128 | 324 ÷ 3 = 108 |
| Regrouping | Changing 1 Hundred into 10 Tens, or 1 Ten into 10 Ones | Page 128 | 2 Tens become 20 Ones |
| Estimate | A sensible guess made before you calculate | Page 124 | Each customer gets less than 100 coconuts |
| Coir | Rope and fibre made from coconut husk | Page 127 | Husk sells at ₹23 per kg |
