1. Rahmiya wants to find how many wheels are on 9 bicycles. Each bicycle has 2 wheels. So, the total number of wheels is calculated by multiplying 9 bicycles by 2 wheels each: $$9 \times 2 = 18$$ Thus, there are 18 wheels on 9 bicycles. 2. Rahmiya's jumps of 2 on the number line represent counting by twos. Starting at 0: 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. We jump every 2 units to reach the number of wheels, 18, at the 9th jump. 3. For the missing numbers: - "12 (ten fewer) 10 (ten more)" Ten fewer than 12 is 2 because $$12 - 10 = 2$$. Ten more than 10 is 20 because $$10 + 10 = 20$$. Thus the missing numbers are 2 and 20 respectively. - "(blank box) (ten more) 8 (ten fewer)" Ten more than 8 is 18 because $$8 + 10 = 18$$. Ten fewer than 8 is -2 because $$8 - 10 = -2$$. So the missing numbers are 18 and -2. 4. For sorting numbers into odd and even circles: - Odd numbers: 13, 5, 15, 1 - Even numbers: 18, 8 5. On Mrs Arain's socks question: She washes 14 socks, which is an even number. She always pegs an odd number of socks, so 14 cannot be pegs all because 14 is even. 6. For shoes: 6 pairs of shoes means $$6 \times 2 = 12$$ shoes. On the number line, starting at 0, count by twos 6 times to reach 12. 7. Write missing numbers for number pattern: - "two fewer <— [14] —> two more" Two fewer than 14 is 12; two more than 14 is 16 - "ten fewer <— [13]" Ten fewer than 13 is 3 because $$13 - 10 = 3$$. Final answers: - Wheels on 9 bicycles: 18 - Missing numbers in question 3: 2, 20, 18, -2 - Odd numbers: 13, 5, 15, 1 - Even numbers: 18, 8 - Mrs Arain cannot peg all socks because 14 is even - Shoes in 6 pairs: 12 - Numbers for two fewer/more of 14: 12 and 16 - Ten fewer than 13: 3
