Answer:

a : b : c = 18 : 30 : 35

Step-by-step explanation:

a : b = 3 : 5

b : c = 6 : 7

Here, b is compared with two different values a and c, to compare a and c, we will take a common multiple of the values of b ( 5 and 6 ).

LCM of 5 and 6 = 30

a : b = 3 : 5

a : b = 3 × 6 : 5 × 6

a : b = 18 : 30

b : c = 6 : 7

b : c = 6 × 5 : 7 × 5

b : c = 30 : 35

( a : b :: b : c = a : b : c )

18 : 30 :: 30: 35

18 : 30 : 35
