Problema Solution
If A:B = 3:4 and B:C = 6:7. Find the ratio of A:B:C.
Answer provided by our tutors
A:B = 3:4
A/B = 3/4
A = B(3/4)
B:C = 6:7
C:B = 7:6
C/B = 7/6
C = B(7/6)
A : B : C = B(3/4) : B : B(7/6) =
= (3/4) : 1 : (7/6) =
= (3*3/(4*3)) : (12/12) : (7*2/(2*6)) =
= 9/12 : 12/12 : 14/12 =
= 9 : 12 : 14
A : B : C = 9 : 12 : 14
