Question 1: List the first 10 multiples of 3.

Answer: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

Question 2: Calculate 7 multiplied by 10. What is the 10th multiple of 7?

Answer: 70

Question 3: Construct a list of the first 10 multiples of 5 on the grid.

Answer: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50

Question 4: Identify the mistake: The first 10 multiples of 4 are listed as 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44.

Answer: The 10th multiple of 4 is 40, but 44 is incorrect; it should be 44 after 40, so the list is correct except for the extra number. The correct first 10 are up to 40, so the mistake is listing 44 as a multiple within the first 10 multiples.

Question 5: What is the 8th multiple of 6? Show your working.

Answer: 6 × 8 = 48

Question 6: List the first 10 multiples of 2. Are all these multiples even numbers? Explain.

Answer: Yes, all multiples of 2 are even numbers because multiplying any number by 2 results in an even number.

Question 7: Plot the graph of y=2x for x=1 to 10 on the grid.

Answer: Coordinates: (1,2), (2,4), (3,6), (4,8), (5,10), (6,12), (7,14), (8,16), (9,18), (10,20)

Question 8: Construct a triangle on the grid with sides equal to the first 10 multiples of 3, ensuring two sides are multiples of 3 and one side is a multiple of 5. (Note: You only need to draw and label the sides appropriately.)

Answer: Students will draw a triangle with sides 3, 6, and 15 (for example), ensuring the lengths reflect multiples.

Question 9: Find the common multiple of 4 and 6 among their first 10 multiples. List all such common multiples within the first 10 multiples of each.

Answer: 12 and 24

Question 10: Identify the 10th multiple of 9. Show your working.

Answer: 9 × 10 = 90

Question 11: What is the least common multiple of 3, 4, and 5? List their first 10 multiples to support your answer.

Answer: The least common multiple is 60. List of first 10 multiples: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30; 4, 8, 12, 16, 20, 24, 28, 32, 36, 40; 5, 10, 15, 20, 25, 30, 35, 40, 45, 50. The smallest common multiple is 60, which appears in the multiples of each.
