Question

If a:b =3:4 and b:c =8:9 , find a:b:c

Answer 1

Step-by-step explanation:

Here a:b=3:4 and b:c = 8:9 . so now we have to do the denominator same for both

so the common term is B

so, a:b=3:4and c:b=9 :8

Now the l.c.m of 4 and 8 is 8

now equalize the denominator with 8 for both ratio

a:b=3/4×2/2=6/8

c:b=9/8×1/1=9/8

so now

A=6

B=8

C=9

so I hope it helps to you
