Answer:
B:C = 3:2
A:B:C = 4:9:6
Step-by-step explanation:
A:B = 4:9
=> A/B = 4/9
A:C = 2:3
=> A/C = 2/3
as A/B = 4/9 => B/A = 9/4
B:C = B/C = (B/A) × (A/C) = (9/4) × (2/3) = 3/2 = 3:2 (1st ans)
as A/B = 4/9 => B = 9A/4
as A/C = 2/3 => C = 3A/2
A:B:C
= A:9A/4:3A/2
= 1:9/4:3/2
= (4×1):(4×9/4):(4×3/2)
= 4:9:6
