a:b=9:5 and b:c=15:3
The figures against b are 5 and 15.
LCM(5,15) = 15
Therefore a:b = begin mathsize 16px style fraction numerator 9 space cross times space 3 space over denominator 5 space cross times space 3 end fraction equals space 27 over 15 end style
and b:c=15:3
Now,
begin mathsize 16px style straight a over straight b space cross times space straight b over straight c equals space 27 over 15 cross times 15 over 3
rightwards double arrow straight a over straight c space equals space 27 over 3 space
rightwards double arrow fraction numerator begin display style straight a end style over denominator begin display style straight c end style end fraction space equals space fraction numerator begin display style 9 end style over denominator begin display style 1 end style end fraction
rightwards double arrow straight a space colon space straight c space equals space 9 space colon space 1
end style
