Now you can write out      ×    

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

-12 × 20 = -240     and 1 × 21 = 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

15% chance.
