Question

if A:B = 1:3 and B:c = 2:3, find A:B:C​

Answer 1

Explanation:-

Given:

• A : B = 1 : 3

• B : C = 2 : 3

To find:

• A : B : C

Solution:

We have,

⟹ A : B = 1 : 3

i.e.,

⟹ A/B = 1/3

⟹ A = (1/3)B - (1)

Also,

⟹ B : C = 2 : 3

i.e.,

⟹ B/C = 2/3

⟹ C = (3/2)B - (1)

Now, A : B : C will be,

⟹ B/3 : B : (3/2)B

⟹ 1/3 : 1 : 3/2

⟹ 1/3 × 6 : 1 × 6 : 3/2 × 6

⟹ 2 : 6 : 9

∴ Ratio of A : B : C is 2 : 6 : 9.
