Question

Bradley is trying to find a missing factor. A product of that factor has a 3 in the ones digit. Is the missing factor even or odd? explain.

Answer 1

Answer:

Odd

Step-by-step explanation:

We are given that

Product of that factor has a ones digit=3

We have to find that missing factor is even or odd.

We know that

Product of two odd numbers is odd.

Product of two even  numbers is even.

Product of one even and one odd number is even.

For example:

$3\times 5=15$

$2\times 4=8$

$2\times 3=6$

If ones digit of a number is odd then the number must be odd.

It means factors of odd number are odd.

If the product of that factor has 3 in the ones digit then, the missing factor will be odd.

Answer 2

That factor is odd because if the last number is odd the whole number is odd
