Question

find a :b: c if a: b is equal to 2:5 and B:C is equal to 4:3​

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.
