Question

if A: b = 5:7 and b:c= 6:11 then A:B:C is ​

Answer 1

Step-by-step explanation:

a : b= 5 : 7=5*6 : 7*6=30 : 42

b : c=6 : 11=6*7 : 11*7=42 : 77

a : b : c=30 : 42 : 77

Answer 2

Answer:

30:42:77

Step-by-step explanation:

A:B = 5:7

and B:C = 6:11

lcm of 7 and 6 = 42

so, A:B = 5*6 : 7*6

            = 30:42

and B:C = 6*7 : 11*7

              = 42:77

Now we got same value for B in both the ratios,

so, A:B:C = 30:42:77
