Question

A man wishes to cover his floor with tiles, each one measuring 3/4

Answer 1

$Area floor = 18 * 12 = 216 feet^2$

$Area tile = 2 * 3/4 = 6/4 = 3/2 = 1.5 feet^2$


$216/1.5 = 144\\ So the answer is A).$

Answer 2

$12\cdot18=216 \ ft^2\leftarrow\hbox{ area of the floor}\\ \frac{3}{4}\cdot2=\frac{3}{2}=1.5 \ ft^2 \leftarrow \hbox{area of a tile}\\\\ \frac{216}{1.5}=144 \Rightarrow A$
