Question

If a:b=3:5 and b:c=6:7, find a:b:c​

Answer 1

Step-by-step explanation:

Given that:-

a:b=3:5-----(1)

a/b=3/5

a/b=18/30

a:b=18:30

and b:c =6:7----(2)

b/c=6/7

b/c=30/35

(On equating the values of b multiplying (1) with 6 and multiplying (2) with 5 then )

a:b =18:30

b:c= 30:35

______________

a:b:c=18:30:35
