I'd feel better if you'd already done some of these problems and shared what you'd gotten.
First problem: A = P (1+r)^t
Here, A = $2000(1+0.03)^5 = $2318.55
Actual W/ actual height= model W/ model height
55 ft/ actual height= 1.5 in./ 15 in,
actual height=55 ft*15 in./1.5 in= 550 ft
(4/7)-(1/3)
(12/31)-(7/21)
(5/21) is left
Or
In decimal form
(4/7)=0.571
(1/3)= 0.333
0.571-0.333
=0.238
