Question

answer the questions below. be sure to mark all answers that apply. (a) which numbers are divisible by 5? (b) which numbers are divisible by 10? (c) which numbers are divisible by 2? 780 454 165 none of these

Explanation:

Step1: Recall divisibility rules

A number is divisible by 5 if its last - digit is either 0 or 5. A number is divisible by 10 if its last - digit is 0. A number is divisible by 2 if its last - digit is even (0, 2, 4, 6, 8).

Step2: Check divisibility by 5

For 780, the last - digit is 0, so it is divisible by 5. For 454, the last - digit is 4, so it is not divisible by 5. For 165, the last - digit is 5, so it is divisible by 5.

Step3: Check divisibility by 10

For 780, the last - digit is 0, so it is divisible by 10. For 454, the last - digit is 4, so it is not divisible by 10. For 165, the last - digit is 5, so it is not divisible by 10.

Step4: Check divisibility by 2

For 780, the last - digit is 0, so it is divisible by 2. For 454, the last - digit is 4, so it is divisible by 2. For 165, the last - digit is 5, so it is not divisible by 2.

Answer:

(a) 780, 165
(b) 780
(c) 780, 454
