students in an art class make square tiles that are five inches wide. they plan to put up a row of the tiles on a wall that is 9 feet 7 inches wide. how many tiles will the student need to make?

Respuesta :

The answer is 12.6. But that doesn't make since it has to be a whole number.
12 is the answer 9x7 is 63÷5 is 12 and 3/5 but you can't make uneven tiled so it is 12
