Ta có: 2a = 3b \(\Rightarrow\frac{a}{3}=\frac{b}{2}\) \(\Rightarrow\frac{a}{9}=\frac{b}{6}\)
4b = 3c \(\Rightarrow\frac{b}{3}=\frac{c}{4}\) \(\Rightarrow\frac{b}{6}=\frac{c}{8}\)
\(\Rightarrow\frac{a}{9}=\frac{b}{6}=\frac{c}{8}=\frac{a+b+c}{9+6+8}=\frac{46}{23}=2\)
\(\Rightarrow a=2.9=18;b=2.6=12;c=2.8=16\)
Vậy a = 18; b = 12; c = 2+
nhầm đây mới đúng
