(c) 125
(d) 639210 (e) 17852​

Answer 1

Answer:

a d b c are there because divisibility test of 5 is the no should end by 0 or 5

Answer 2

Given:

a. 438750

b. 179015

c, 125

d. 639210

e. 17852​

What to find?

Find out whether these nubmers are divisible by 5.

How to find?

To determine if the numbers are divisible by 5 check the last digit of the number. If the last digit is either 5 or 0, then it is divisible by 5.

Solution:

a.  438750

⇒ Check the last digit i.e., 0.

∴ Yes, it is divisible by 5.

b. 179015

⇒ Check the last digit i.e., 5

∴ Yes, it is divisible by 5.

c. 125

⇒ Check the last digit i.e., 5.

∴ Yes, it is divisible by 5.

d. 639210

⇒ Check the last digit i.e., 0.

∴ Yes, it is divisible by 5.

e. 17852​

⇒ Check the last digit i.e., 2.

∴ No, it is not divisible by 5.
