Carrie needs to determine the number of tiles that will fit in each row along the back of the shower. if the back of the shower measures 6 feet long and each tile 2/3 of a foot long, which equation shows how to determine the number of tiles that will fit in each row?

Option A

Explanation:
We know that one tile is 2/3 ft long and we want to cover 6 ft (which is the given measure of the back of the shower).

To know the number of tiles needed, we will simply do cross multiplication as follows:
1 tile > 2/3 ft
?? tiles > 6 ft

Number of tiles = (6*1) / (2/3)
Number of tiles = 6 / (2/3)
Number of tiles = 9 tiles

Hope this helps :)
