0 and 5 only at the last of any number

Answer 2

The answer is 0 or 5.

A number is divisible by 5 if its unit digit is 0 or 5.

• Divisibility refers to the characteristic where a number divided by another number gives the remainder as zero. In such a case, the dividend is said to be divisible by the divisor.

• In the multiplication table of five, we see that all the products either end with zero or five. Some of the multiples of five are 10, 15, 20, 25, and so on. Thus, we see that all the numbers either end with zero or five.

• The numbers in the ten's places do not matter as long as the number has zero or five in the unit's place. Thus, a number that is divisible by five should have the numbers zero or five in the unit's place.
