Answer 1

In the present question, it is required to calculate 7/8 of 160, because it is the number of magazines sold yesterday.

From this, we perform the calculation as follows:

`\begin{gathered} (1)/(8)of\text{ }160=(160)/(8)=20 \\ (7)/(8)of160=7*(1)/(8)\text{ of }160=7*20=140 \end{gathered}`

From the solution presented above, we are able to conclude that the number of copies sold yesterday was 140.
