Answer 3

\(a,\) \(\frac{48}{64}+\frac{7}{4}=\frac{3}{4}+\frac{7}{4}=\frac{5}{2}\) 

\(b,\)  \(\frac{3}{8}+\frac{119}{56}=\frac{3}{8}+\frac{17}{8}=\frac{5}{2}\)

Rút gọn đi bn ơi

Answer 6

\(a,\frac{48}{64}+\frac{7}{4}=\frac{3}{4}+\frac{7}{4}=\frac{10}{4}=\frac{5}{2}\)

\(b,\frac{3}{8}+\frac{119}{56}=\frac{3}{8}+\frac{17}{8}=\frac{20}{8}=\frac{10}{4}=\frac{2}{5}\)
