The factors have the same sign.

Step-by-step explanation-

If both of the numbers are negative, the product will become positive. If both the numbers are positive, the product will stay positive.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
