Answer 2

Answer: a:b:c= 12:18:5

Step-by-step explanation:

Given that a:b = 4:6

$\dfrac{a}{b} =\dfrac{4}{6}-----(i)$

b:c= 18:5

$\dfrac{b}{c} =\dfrac{18}{5}-----(ii)$

Now to make the denominator of (i) and numerator of (ii) equal

\$\dfrac{a}{b} =\dfrac{4}{6}\text { and } \dfrac{b}{c} =\dfrac{18}{5}\\\\\Rightarrow \dfrac{a}{b} =\dfrac{4\times 3}{6\times 3} \text { and } \dfrac{b}{c} =\dfrac{18}{5}\\\\\Rightarrow \dfrac{a}{b} =\dfrac{12}{18} \text { and } \dfrac{b}{c} =\dfrac{18}{5}$

Therefore a:b:c= 12:18:5
