To find the weight of each paperweight, divide the total weight by the number of paperweights:

$\frac{0.8 \, \text{pounds}}{5 \, \text{paperweights}} = 0.16 \, \text{pounds per paperweight}.$

So, each paperweight weighs 0.16 pounds.

Would you like more details or have any questions?

Here are some related questions to consider:

1. If Cara bought 3 more paperweights with the same weight, what would their total weight be?
2. How much would 10 of these paperweights weigh together?
3. If each paperweight weighed 0.25 pounds instead, what would be the total weight for 5 paperweights?
4. If two of the paperweights were damaged and weighed half their original weight, what would their combined weight be?
5. How many paperweights would it take to reach a total of 1 pound if each weighs 0.16 pounds?

Tip: To check your work with division problems, multiply your answer by the divisor to see if it matches the original total!
