3. Divisible
4. Divisible
5. Divisible
6. Not Divisible
7. Divisible
Step-by-step explanation:
<u>Question 2. Is 629,257 divisible by 5?</u>
- Numbers that are divisible by 5 should end with either 5 or 0.
- The ending term of [629,25<u>7</u>] is 7, which is neither 5 nor 0. Therefore, it is <u>not divisible</u>.
<u>Question 3. Is 3,791,916 divisible by 2?</u>
- Numbers that are divisible by 2 should end with an even number or 0, which include 0, 2, 4, 6, 8.
- The ending term of [3,791,91<u>6</u>] is 6, which is an even number. Therefore, it is <u>divisible</u>.
<u>Question 4. Is 63,726,125 divisible by 5?</u>
- Numbers that are divisible by 5 should end with either 5 or 0.
- The ending term of [63,726,12<u>5</u>] is 5. Therefore, it is <u>divisible</u>.
<u>Question 5. Is 486,342 divisible by 3?</u>
- In numbers that are divisible by 3, the sum of all digits is a multiple of 3.
- The sum of all digits of [486,342] is [4 + 8 + 6 + 3 + 4 + 2 = 27].
- 27 / 3 = 9
- Since the sum of all digits is divisible by 3, then 486,342 is <u>divisible </u>by 3.
<u>Question 6. Is 474,493 divisible by 10?</u>
- Numbers that are divisible by 10 should end with 0.
- The ending term of [474,493] is 3, which is not 0. Therefore, it is <u>not divisible</u>.
<u>Question 7. Is 53,017,587 divisible by 9?</u>
- In numbers that are divisible by 9, the sum of all digits is a multiple of 9.
- The sum of all digits of [53,017,587] is [5 + 3 + 0 + 1 + 7 + 5 + 8 + 7 = 36].
- 36 / 9 = 4
- Since the sum of all digits is divisible by 9, then 53,017,587 is <u>divisible</u> by 9.
