Answer
Answer:
- 3, 6, 9, 12, 15, 18, 21, 24
- 7, 14, 21
Explanation:
Step1: Recall multiple - definition
A multiple of a number $n$ is a number that can be written as $n\times k$ where $k$ is an integer.
Step2: Check multiples of 3
For 3: $3 = 3\times1$, 6: $6 = 3\times2$, 9: $9 = 3\times3$, 12: $12 = 3\times4$, 15: $15 = 3\times5$, 18: $18 = 3\times6$, 21: $21 = 3\times7$, 24: $24 = 3\times8$.
Step3: Check multiples of 7
For 7: $7 = 7\times1$, 14: $14 = 7\times2$, 21: $21 = 7\times3$.
