Question

answer the questions below. be sure to mark all answers that apply. (a) which numbers are divisible by 3? (b) which numbers are divisible by 9? 853 739 301 none of these

Explanation:

Step1: Recall divisibility rule for 3

A number is divisible by 3 if the sum of its digits is divisible by 3.
For 853: $8 + 5+3=16$, 16 is not divisible by 3.
For 739: $7 + 3+9 = 19$, 19 is not divisible by 3.
For 301: $3+0 + 1=4$, 4 is not divisible by 3.

Step2: Recall divisibility rule for 9

A number is divisible by 9 if the sum of its digits is divisible by 9.
For 853: $8 + 5+3=16$, 16 is not divisible by 9.
For 739: $7 + 3+9 = 19$, 19 is not divisible by 9.
For 301: $3+0 + 1=4$, 4 is not divisible by 9.

Answer:

(a) None of these
(b) None of these
