\(\frac{2}{3}\) + \(\frac{3}{4}\) = \(\frac{8}{12}\) + \(\frac{9}{12}\) = \(\frac{17}{12}\)
\(\frac{5}{6}\) x \(\frac{4}{15}\) = \(\frac{2}{9}\)
\(\frac{4}{5}\) - \(\frac{2}{7}\) = \(\frac{28}{35}\) - \(\frac{10}{35}\) = \(\frac{18}{35}\)
\(\frac{13}{9}\) : \(\frac{5}{6}\) = \(\frac{13}{9}\) x \(\frac{6}{5}\) = \(\frac{26}{15}\)
chúc bạn hok tốt !
\(\frac{2}{3}+\frac{3}{4}=\frac{8}{12}+\frac{9}{12}=\frac{17}{12}\)
\(\frac{5}{6}\) x \(\frac{4}{15}\) \(=\frac{5x6}{6x15}=\frac{1}{3}\)
\(\frac{4}{5}-\frac{2}{7}=\frac{28}{35}-\frac{10}{35}=\frac{18}{35}\)
\(\frac{13}{9}:\frac{5}{6}=\frac{13}{9}x\frac{6}{5}=\frac{13x6}{9x5}=\frac{26}{15}\)
Chúc bạn học tốt !
viết phân số như thế kiều gì thế các bạn ?
