Question: Bruno wants to buy two and one-half dozens of pens. How many pens will he have? Think carefully first, then make a decision:
Since a dozen is equal to 12, then two dozens are equal to 12 x 2 = 24. One - half dozen is equal to 12 / 2 = 6. Thus, Bruno will have a total of 24 + 6 = 30 pens. So the answer is 30.
