Answer:

A

Explanation:

In order to multiply a whole number by a fraction, you can write the whole number in fraction form. -12 can also be written as
(-12)/(1).

Now you can write out
(-12)/(1) ×
(20)/(21)

Multiply the numerators by each other and the denominators by each other to create one fraction.

-12 × 20 = -240 and 1 × 21 = 21


(-12)/(1) ×
(20)/(12) =
(-240)/(21) and now you can simplify the fraction by finding the greatest common factor of the denominator and numerator. -240 and 21 have the greatest common factor of 3. Divide each side by 3 and get the fraction -80/7
