Final answer:
Herman bought a bag of parsnips weighing 4 3/5 pounds. Multiplying this by 4, since the turnips weighed four times as much, the total weight of the turnips is 18 2/5 pounds.
Step-by-step explanation:
Herman bought a bag of parsnips weighing 4 3/5 pounds. To find out how much the turnips weighed, we need to calculate four times the weight of the parsnips. Since 4 3/5 equals 23/5 when converted to an improper fraction, we simply need to multiply this by 4:
23/5 × 4 = 92/5
92/5 is an improper fraction, and when converted to a mixed number, it equals 18 2/5 pounds. Therefore, Herman bought 18 2/5 pounds of turnips.
