6. [tex]1 \frac{1}{2} = \frac{6}{4} [/tex] since [tex] \frac{1}{4} = 4 [/tex] feet. Then 6*4=24 So the answer is C
7. 1200 m/8 cm = C. 1 cm = 150 m
8. A. Since 1 in = 3 feet then 6 inches = 18 feet (6*3=18) and 4 inches = 12 feet (4*3=12) so the dimensions of her room are 16'x12'.
B. A=lxw so 16*12= 216 [tex] m^{2} [/tex]
Hope that helps
