1.
1/4 < 1/3 < 1/2
A receives 7800*(1/4)/(1/4 + 1/2 + 1/3) = 7800*(1/4)/(13/12) = 7800*(1/4)(12/13) = 7800*3/13 = 1800
2.
There're errors in this question. It has to have "=" somewhere.
3.
a)
At the scale of 1cm:6m, the length is 5.8*6 = 34.8m; the height is 3.6*6 = 21.6 m
b)
n : 1 = 5.8 : 3.6
n = 1*5.8/3.6 = 1.61
