Q1.
In a big aquarium, Jolly fish sees 72 legs of octopuses. How many octopuses are there in the aquarium?
Answer
The picture in the book: a big aquarium with water plants and rocks, a few octopuses swimming, and Jolly the fish watching them. Each octopus has 8 legs.

There are 9 octopuses in the aquarium.

One octopus has 8 legs, so we find 72 ÷ 8.
5 octopuses use 5 × 8 = 40 legs. 72 − 40 = 32 legs left.
4 octopuses use 4 × 8 = 32 legs. 32 − 32 = 0 legs left.
Total = 5 + 4 = 9 octopuses
Check: 9 × 8 = 72 ✓
Why it happens: Each octopus takes away one group of 8 legs, so the number of groups of 8 inside 72 is the number of octopuses.
Q2.
A sports store packs 4 shuttlecocks in a bigger box. They have 50 shuttlecocks. How many boxes will they need to pack all of them? Can they pack all the shuttlecocks in the boxes? How many are left?
Answer
Boxes of 4 shuttlecocks each.

12 boxes get filled and 2 shuttlecocks are left over.

50 ÷ 4
10 boxes use 10 × 4 = 40 shuttlecocks. 50 − 40 = 10 left.
2 more boxes use 2 × 4 = 8 shuttlecocks. 10 − 8 = 2 left.
Boxes filled = 10 + 2 = 12, shuttlecocks left = 2

No, they cannot pack all of them in full boxes. The 2 left over need one more box, which will not be full.

Why it happens: 50 is not made of whole groups of 4. After 12 whole groups, 2 are left over — that leftover is the remainder.
Q3.
Rakul Chachi uses a part of her farm to grow flowering plants for the upcoming festive season. She has planted 75 saplings of roses. Each row has 5 saplings. How many rows of saplings has she planted?
Answer
Rows of rose saplings with 5 saplings in each row.

She has planted 15 rows.

75 ÷ 5
10 rows use 10 × 5 = 50 saplings. 75 − 50 = 25 left.
5 rows use 5 × 5 = 25 saplings. 25 − 25 = 0 left.
Total rows = 10 + 5 = 15
Check: 15 × 5 = 75 ✓
Tip: Count in 5s and keep a tally: 5, 10, 15 … 75. You will tick 15 times.
Q4.
Make stories for the following problems and solve them: a) 70 ÷ 5 b) 84 ÷ 7 c) 69 ÷ 3 d) 93 ÷ 6
Answer

Sample stories and answers:

  • a) 70 ÷ 5 — 70 laddoos are packed 5 in a box. How many boxes?
  • b) 84 ÷ 7 — 84 days is how many weeks (7 days each)?
  • c) 69 ÷ 3 — 69 wheels are fixed on rickshaws with 3 wheels each. How many rickshaws?
  • d) 93 ÷ 6 — 93 pencils are shared among 6 children. How many each?
a) 70 ÷ 5: 10 fives = 50, 4 more fives = 20, 50 + 20 = 70 → 14
b) 84 ÷ 7: 10 sevens = 70, 2 more sevens = 14, 70 + 14 = 84 → 12
c) 69 ÷ 3: 20 threes = 60, 3 more threes = 9, 60 + 9 = 69 → 23
d) 93 ÷ 6: 15 sixes = 90, and 3 are left → 15 and 3 left over
Check it yourself: 14 × 5 = 70, 12 × 7 = 84, 23 × 3 = 69, and 15 × 6 + 3 = 93.
