Question

13. IFA:B = 3:2 and B:C-3:5, then A:B:Cis
(a) 9: 6:10
(b) 6:9:10
(c) 10:9:6​

Answer 1

Answer

9: 6:10

Step-by-step explanation:

A:B = 3:2  

B=2 when A=3

B:C = 3:5

B=3 when C=5

But to connect the two ratios you need B to be the same number in both. Find the Least Common Multiple.

LCM(2, 3) = 6

Now scale the equations so that B becomes 6.

A:B = 3:2 = 9:6

B:C = 3:5 = 6:10

A:B:C = 9:6:10
