Answer: a) 1 : 1.5
Step-by-step explanation:
you can go from one rectangle as a ratio.
little one is rectanggle A
bigger one is rectangle B
if A is taken as the unit you can try equations
so: 1 : x
2*x = 3 and 5*x = 7.5
it has to be correct in both equations
therefore:
x=3/2 = 1.5
and you can see:
5*1.5 = 7.5
so: 1 : 1.5
