Question

Ben says that when any number between 1 and 9 is multiplied by 5, the product always has a 0 of 5 in the ones place. Is this reasonable

Answer 1

Answer: Yes, it's reasonable.

Explanation:

5 x 1 = 5

5 x 2 = 10

5 x 3 = 15

5 x 4 = 20

5 x 5 = 25

5 x 6 = 30

5 x 7 = 35

5 x 8 = 40

5 x 9 = 45

Answer 2

Ben's statement is not accurate. When you multiply any number between 1 and 9 by 5, you will get a product with a 5 in the ones place only when the original number ends in 1, 2, 3, 4, 6, 7, 8, or 9. For example:

- 1 multiplied by 5 equals 5.

- 2 multiplied by 5 equals 10.

- 3 multiplied by 5 equals 15.

- 4 multiplied by 5 equals 20.

- 6 multiplied by 5 equals 30.

- 7 multiplied by 5 equals 35.

- 8 multiplied by 5 equals 40.

- 9 multiplied by 5 equals 45.

So, there are cases where the product has a 5 in the ones place, but it's not true for every number between 1 and 9.
