Multiplying the weight of a coing by the number of coins, we have:


\begin{gathered} (4)/(5)\cdot(7)/(1)=(28)/(5)\text{ (Multiplying fractions)} \\ \text{Converting the fraction to a mixed number, we have: } \\ 28/\text{ 5 -> Quotient: 5, Remainder: 3 } \\ 28/5\to\text{ 5}(3)/(5) \\ \text{The answer is 5}(3)/(5) \end{gathered}
