Question

A sidewalk is built 12 bricks wide by laying each brick side by side. How many inches wide is the sidewalk if each brick measures 2 5/16 inches wide?

Answer 1

Here we need to multiply 2 5/16 inches/brick by 12 bricks.

Converting 2 5/16 inches into an improper fraction, we get 37/16 inches;
multiplying that by 12 (bricks) results in a walkway width of 27.75 inches, or 27 3/4 inches.
