A photograph must be reduced to four-fifths of its original size to fit the space available on a particular flyer. If the original width of the photograph was inches, what must its new width be?

Solution:
1. Let the original width of the photograph be x inches.
2. The photograph must be reduced to four-fifths of its original size.
3. Calculate the new width as follows:
\text{New width} = \frac{4}{5} \times x inches.

Thus, the new width of the photograph is \\frac{4}{5} x \ inches.
