Explanation:

Step1: Find weight of one package

A package has 300 pieces, each piece is \(9.9\times10^{-3}\) pounds. So weight of one package is \(300\times(9.9\times10^{-3})\).
\(300\times9.9\times10^{-3}=2970\times10^{-3}=2.97\) pounds.

Step2: Find weight of 5 packages

Now, multiply weight of one package by 5: \(5\times2.97 = 14.85\) pounds.

Answer:

14.85 pounds
