Question

If a:b=3:4 and b:c=8:9 then find a:c. Also express a:b:c in simplest form​

Answer 1

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., 4 and 6.

L.C.M. of 4 and 6=12

Therefore, an equivalent ratio of A:B=3:4=3×3:4×3=9:12

Similarly, an equivalent ratio of B:C=6:7=6×2:7×2=12:14

Therefore,A:B:C=9:12:14

Answer 2

Answer:

a:c = 1:3

Step-by-step explanation:

a 3 1

__ = __ = __

c 9 3

therefore a:c = 1:3
