\(\frac{a}{2}=\frac{b}{\frac{3}{2}}=\frac{c}{\frac{4}{3}}=\frac{a-b}{2-\frac{3}{2}}=\frac{15}{\frac{1}{2}}=30\)

a = 30,2 = 60

b =30.3/2 =45

c =30.4/3 =40 

a=60;b=45;c=40

mk k hiểu câu trả lời của bn oh yeah

\(\frac{a}{2}=\frac{b}{\frac{3}{2}}=\frac{c}{\frac{4}{3}}=\frac{a-b}{2-\frac{3}{2}}=\frac{15}{\frac{1}{2}}=30\)

\(\Rightarrow a=30.2=60\)

\(\Rightarrow b=30.\frac{3}{2}=45\)

\(\Rightarrow c=30.\frac{4}{3}=40\)

\(\frac{a}{2}\)=\(\frac{b}{\frac{3}{2}}\)=\(\frac{c}{\frac{4}{3}}\)=\(\frac{a-b}{2-\frac{3}{2}}\)=\(\frac{15}{\frac{1}{2}}\)=30

a=30.2=60

b=30.\(\frac{3}{2}\)=45

c=30.\(\frac{4}{3}\)=40
