Nancy bought a bag of parsnips that weighed 4 1/2
pounds. She also bought a bag of turnips that weighed 4 times as much as the parsnips. How many pounds of turnips did Nancy buy?
To find out how much the bag of turnips weighed, we need to multiply the weight of the parsnips by 4.
4 1/2 * 4 = 18
Therefore, Nancy bought 18 pounds of turnips.
