Vedclass · Answer

(B) Given $A : B = 7 : 9$ and $B : C = 8 : 11$.To find $A : B : C$,we need to make the value of $B$ common in both ratios.The value of $B$ in the first ratio is $9$ and in the second ratio is $8$.The least common multiple $(LCM)$ of $9$ and $8$ is $72$.Multiply the first ratio by $8$:$A : B = (7 	imes 8) : (9 	imes 8) = 56 : 72$Multiply the second ratio by $9$:$B : C = (8 	imes 9) : (11 	imes 9) = 72 : 99$Now,combining both ratios,we get:$A : B : C = 56 : 72 : 99$.

If $A : B = 7 : 9$ and $B : C = 8 : 11,$ find $A : B : C$.
