Solution
We have b common in both fractions  Equating b by multiplying a/b with 12 and b/c with 11  a/b = (7/11) x 12 = 84/132  b/c (12/17) x 11 = 132/187 So, a: b:c=84: 132: 187 Now, a+b=84+132=216 units And b+c=132+187=319 units (a+b)/(b+c) = 216/319 Hence, the value of (a + b)/(b + c) is 216/319.
