A sales table at Anthony's department store contains a pile of sweaters, 12 medium size and 20 small size. A sweater is selected at random. Fine the probability that it is a small size

There is a 20:12 chance that there is a small size, now that would be a answer but I suggest simplifying the answer so divide them by 4 since that's the greatest common factor. So, 20/4=5 & 12/4=3 so there is a 4:3 chance that you get a small sized sweater.

The answer is 4:3 chance
