Step-by-step explanation:
25/4*14*3= 21*25/4= 262.5 ft^3
3/10+ 5/8
First find a common denominator
multiply top and bottom the same
12/40 +25/40
add
37/40
Ratio in the first sample = 250/1000 = 1/4 = 0.25
ratio in the second sample = 750/2000 = 0.375
hence ,<span> there is a greater proportion of smokers in the second city than in the first.

hope this helps!!
