Question

At a copy place there are 15 copy machines in a row with no space between them. Each copier is 3 feet 3 inches across. What is the total length of the 15 copy machines

Answer 1

Visualize this arrangement or, better yet, make a sketch, showing fifteen rectangles side by side, with the length of each rectangle being 3¼ ft.  How long is that?  Either add fifteen equal values, or use MULTIPLICATION.
