which of these numbers are multiples of 3? choose all that apply. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17…

Answer:

3, 6, 9, 12, 15, 18, 21, 24

Explanation:

Step1: Recall multiple - definition

A multiple of 3 is a number that can be written as 3n where n is an integer.

Step2: Check each number

For 1: $1\div3=\frac{1}{3}$, not a multiple. For 2: $2\div3=\frac{2}{3}$, not a multiple. For 3: $3 = 3\times1$, is a multiple. For 4: $4\div3=\frac{4}{3}$, not a multiple. For 5: $5\div3=\frac{5}{3}$, not a multiple. For 6: $6 = 3\times2$, is a multiple. For 7: $7\div3=\frac{7}{3}$, not a multiple. For 8: $8\div3=\frac{8}{3}$, not a multiple. For 9: $9 = 3\times3$, is a multiple. For 10: $10\div3=\frac{10}{3}$, not a multiple. For 11: $11\div3=\frac{11}{3}$, not a multiple. For 12: $12 = 3\times4$, is a multiple. For 13: $13\div3=\frac{13}{3}$, not a multiple. For 14: $14\div3=\frac{14}{3}$, not a multiple. For 15: $15 = 3\times5$, is a multiple. For 16: $16\div3=\frac{16}{3}$, not a multiple. For 17: $17\div3=\frac{17}{3}$, not a multiple. For 18: $18 = 3\times6$, is a multiple. For 19: $19\div3=\frac{19}{3}$, not a multiple. For 20: $20\div3=\frac{20}{3}$, not a multiple. For 21: $21 = 3\times7$, is a multiple. For 22: $22\div3=\frac{22}{3}$, not a multiple. For 23: $23\div3=\frac{23}{3}$, not a multiple. For 24: $24 = 3\times8$, is a multiple.
