Final answer:
Ms. Gregory bought 12 ounces of lemons after converting ¾ pound to ounces using the conversion factor of 16 ounces per pound.
Step-by-step explanation:
To find out how many ounces of lemons Ms. Gregory bought, we must convert the weight from pounds to ounces. Since there are 16 ounces in one pound, we can use this conversion factor to perform the calculation. For ¾ lb of lemons, we multiply by the conversion factor as follows:
- ¾ lb × 16 oz/lb = ¾ × 16 oz
- That is, (0.75 × 16) oz = 12 oz
Therefore, Ms. Gregory bought 12 ounces of lemons at the supermarket.
