(e) Q = 121, R = 2
1. Draw 4 oranges on each 5 plates. (g) Q = 115, R = 0 (h) Q = 139, R = 3
There will be 4 oranges in each plate. (i) Q = 100, R = 6 (j) Q = 207, R = 1
So, 20 ÷ 5 = 4. (k) Q = 173, R = 2 (l) Q = 107, R = 1
2. Draw 3 candles on each cake. Exercise 6.7
There will be 3 candles on each cake. 1. 31 tents, 1 child left
So, 27 ÷ 9 = 3. 2. 29 packets, 4 chocolates left 3. 35 bags
3. Draw 4 boxes and put 3 balls in each box. 4. 24 bags 5. 15 6. 35
There will be 4 boxes. 7. (a) to (h) Students to write their own answer.
So, 12 ÷ 3 = 4. Let’s Evaluate
