Answer: The product of 5 and an odd number will end with the value of 5.
Explanation:
We are given a number which is '5'
When we multiply the number '5' with a digit, the unit place will have wither '5' or '0'
When the number getting multiplied by '5' is even (0, 2, 4, 6 or 8), then the units place will have 0.
For Example: Multiplying 62 with 5, we get, (62 × 5) = 310
When the number getting multiplied by '5' is odd (1, 3, 5, 7 or 7), then the units place will have 5.
For Example: Multiplying 23 with 5, we get, (23 × 5) = 115
Hence, the product of 5 and an odd number will end with the value of 5.
