A sidewalk is built 12 bricks wide by laying each brick side by side.
The size of each brick measures [tex]3\frac{3}{8}[/tex]
Convert the mixed fraction into improper fraction
[tex]3\frac{3}{8}= \frac{27}{8}[/tex]
The width of each brick is [tex]\frac{27}{8}[/tex]
To built side walk, 12 bricks are used
To find the width of side walk , we multiply the number of bricks with the width of each brick
[tex]12 * \frac{27}{8}[/tex]
We can cancel out 12 and 8
[tex]3 * \frac{27}{2}[/tex]
[tex]\frac{81}{2}[/tex]
[tex]40\frac{1}{2}[/tex] inches
