Question

A:B =6:11 and B:C =1:3, then A:C is​

Answer 1

A:B = 6:11

$\bold {\implies{ \frac{A}{B} = \frac{6}{11} }}$

and,

B:C = 1:3

$\bold{ \implies{ \frac{B}{C} = \frac{1}{3} }}$

so,

$\bold {A:C \implies \frac{A}{C} = \frac{ \cancel 6 \:² }{ \cancel3} }\\ \\ \implies \frac{2}{1} = \purple{2:1}$
