Final answer:
The total weight of 1½ jars of peanut butter is 12.45 ounces, calculated by multiplying 8.3 ounces by 1.5.
Step-by-step explanation:
To find the total weight of 1½ jars of peanut butter, given that a single jar weighs 8.3 ounces, you first have to multiply the weight of one jar by the number of jars. In this case, it's 1.5 jars times 8.3 ounces.
First, calculate the weight:
- 8.3 ounces per jar × 1.5 jars = 12.45 ounces
Therefore, the total weight of 1½ jars of peanut butter is 12.45 ounces. This illustrates a basic principle of unit conversion in customary measurement where you multiply the number of units by the unit equivalence to get the total.
