Starting from the top left.

(1) The ratio between the surface area of the SF^2= SA small/SA big = t/f=16/64 = 1/4

Thus SF = sqrt(1/4)=1/2 (or 1:2)

(2) SF = sqrt(288/1152)=sqrt(1/4)=1/2 (or 1:2)

(3) SF^3= 896/4802 SF=3rd root( 896/4802)=4/7 (or 4:7)

(4) SF = 3rd toot (5616/26000) = 3/5 or (3:5)

Good Luck!
