Question

if b/a=2 and c/b=3 then what is the ratio of a+b to b+c​

Answer 1

Answer:

a:b=2:3,

b:c=4:5

When we want the combined ratio of these kind of ratios like a:b:c, we do have a small trick.

In a:b:c the ratio component of ‘a’ will be the product of compnent of ‘a’ in a:b and component of ‘b’ in b:c I.E., 2*4=8. a=8.

Component of ‘b’ will be product ‘b’ components in both the ratios I.E., 4*3=12. b=12

Component of c will be product of Component of b in a:b and c component in b:c I.E., 5*3=15. C=15

Answer 2

Step-by-step explanation:

b : a c : b

2 : 1 3 :1

a : b : c

1 : 2 : 2

1 : 1 : 3

1 : 2 : 6 = a : b : c

a+ b =3 , b+c =8

a+b : b+c

3 : 8
