First, let's find out how many 5/6 pound bags he can fill with one 2 pound bag. 2 ÷ 5/6 2 × 6/5 2.4 He can fill 2.4 bags with one 2 pound bag. Now, we just need to multiply 2.4 by a number that will make it a whole number. We'll use guess and check. 2.4 × 2 = 4.8 2.4 × 3 = 7.2 2.4 × 4 = 9.6 2.4 × 5 = 12 12 is a whole number. This means that Chad needs to buy 5 of the 2 pound bags to fill 12 of the 5/6 pound bags, and he will have not peanuts leftover.
