Question

Using divisibility tests , determine which of the following numbers are divisible by 5(a) 438750
(b) 179015
(c) 125
(d) 639210
(e) 17852

Answer 1

Answer:

all except the last one

Step-by-step explanation:

because a no. is divisible by 5 only when it's unit digit is 5 or 10

Answer 2

438750, 179015, 125 and 639210 are divisible by 5

Step-by-step explanation:

The test for divisibility by 5 is that the number should have either 5 or 0 on the one's place.

So, the numbers that fulfill the above condition are 438750, 179015, 125 and 639210. They have 5 or 0 in their one's place. Hence these numbers are divisible by 5.

However, 17852 does not have 5 or 0 in the one's place. So this number is not divisible by 5.
