... 1. A good strategy is to start with multiples of 10 because they are “easy” numbers with which to work. Ask: Are there at least 20 [12s]? Yes, because 20 12 240 Are there more than 30 [12s]? No, because 30 12 360 So, the answer is at least 20 but not more than 30. Try 20, because 20 is the f ...
