The answer is 12 divided by 3/8, total weight of all patties divided by weight of each patty. Division is equivalent to multiplication if you invert the divisor and change to multiplication, then the answer is 12 times 8/3. 12/(3/8) = 12 x 8/3 = 12x8/3 = 12/3 x 8 = 4 x 8 = 32 patties. Then Check your answer 32 patties each weighing 3/8 means total weight is 32 times 3/8 = 32x3/8 = 32/8 x 3 = 4 x 3 = 12 pounds. It's also useful to estimate the answer to make sure you're in the right ball park. If each patty weighed 1 pound, it's more obvious there's 12 patties as 12 x 1 = 12 = total weight. If each patty weighed 1/2 pound, you'd have twice as many patties, or 12x2=24. 3/8 is slightly less than 1/2, so you'd have more than 24 patties. 32 is more than 24. This helps on multiple choice tests where if you can at least eliminate some answers as too small or too large, you can improve the odds of getting the right answer or know when to recheck your calculations.
