If A:B = 6:5 and B:C = 4:1, find A:B:C.
In the given ratios "B" is the common term, and the values of B in both ratios are not equal. To make them equal, find the L.C.M. of values corresponding to B i.e., 5 and 4.
L.C.M. of 5 and 4 = 20
Therefore, A:B = 6:5 = 6x4:5x4 = 24:20.
B:C = 4:1 = 4x5:1x5 = 20:5.
Therefore, A:B:C = 24:20:5.
