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 meaaures 3 3/8 inches wide?

Answer 1

A sidewalk is built 12 bricks wide by laying each brick side by side.

The size of each brick measures
`3(3)/(8)`

Convert the mixed fraction into improper fraction

`3(3)/(8)= (27)/(8)`

The width of each brick is
`(27)/(8)`

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

`12 * (27)/(8)`

We can cancel out 12 and 8

`3 * (27)/(2)`

`(81)/(2)`

`40(1)/(2)` inches
