Pg 314 (326) - Q16
It says that AxBxC=72. It says that they are integers with A being the greatest followed by B and C. What is the greatest possible value of A? To get the greatestpossible value of A, you need the least possible value of B and C. Therefore, if you set up B and C(each have to be integers greater than 1, and one greater than the other), C would be equal to 2, and B would be equal to 3. 3X2=6, and 6 goes into 72 twelve times; therefore, you have A, 12 is the correct answer.
