Question

A number is divisible by 25 Is it also divisible by 5 ? Give reasons for your answer​

Answer 1

Answer:

Yes

Explanation:

Because every number which is divisible by 25 will have 5 or 0 at the units place and the numbers which have either 0 or 5 at the units place are always divisible by 5.

Answer 2

Answer:

Yes, all of the numbers completely divisible by 25 are also completely divisible by 5.

Explanation:

The given number is divisible by 25, i.e., it is following the divisibility rule of 25 which says that the number is divisible by 25 if it is ending by the digits 00, 25, 50, 75.

Now, we know that the divisibility rule of 5 says that the number is divisible by 5 as long as the digit at ones place is either 0 or 5.

Now, comparing the divisibility rule of 25 to that of 5 we can clearly say that the divisibility rule of 25 includes the divisibility by 5 as all of the digits 00, 25, 50, 75 are ending with either 0 or 5 at the end.

Thus, all of the numbers divisible by 25 are also divisible by 5.
