bài 1 : tính phân số:
a) \(\frac{5}{7}+\frac{4}{9}=?;\frac{4}{5}-\frac{2}{3}=?;\frac{9}{11}+\frac{3}{8}=?;\frac{16}{25}-\frac{2}{5}=?\)=?
b)\(5+\frac{3}{5}=?;10-\frac{9}{16}=?;\frac{2}{3}-\left(\frac{1}{6}+\frac{1}{8}\right)=?\)
c)\(\frac{5}{7}+\frac{7}{6}=?;\frac{7}{12}+\frac{17}{18}=?;\frac{9}{8}+\frac{15}{32}=?;4+\frac{35}{45}=?\)
d)\(\frac{11}{4}-\frac{15}{16}=?;\frac{5}{6}-\frac{5}{8}=?;\frac{196}{64}-2=?;3-\frac{13}{9}=?\)
e)\(\frac{8}{5}+\frac{7}{6}+\frac{5}{9}-2=?;3-\frac{5}{6}-\frac{4}{9}+\frac{32}{24}=?\)
Cộng phân số;
\(\frac{1}{6}+\frac{5}{6}\)
\(\frac{25}{5}+\frac{2}{6}\)
\(\frac{12}{5}+\frac{6}{9}\)
\(5\frac{5}{6}+6\frac{5}{6}=?\)
\(\frac{6}{5}+\frac{5}{6}+\frac{4}{7}=\)
\(\frac{1}{8}\times\frac{5}{6}+\frac{5}{6}\times\frac{2}{3}\)
