Question

Answer 1

20:27

First of all make the two ratios in the common form nd solve the ratio

Answer 2

Answer: 20:27

Step-by-step explanation:

A : B = 2: 3  .....(i)

B : C = 4 : 5 .... (ii)

Make the values of 'B' same.

Multiply (i) by '4' && (ii) by '3'

(i)==== A : B = 2*4 : 3*4 = 8 : 12

(ii)=== B : C = 4*3 : 5*3 = 12 : 15

A : B : C = 8 : 12 : 15

(A+B) : (B+C) = (8+12): (12+15) =  20 : 27
