Đúng ko
K mk nha
\(2\frac{3}{5}=\frac{13}{5}\)
\(5\frac{4}{9}=\frac{49}{9}\)
\(9\frac{3}{8}=\frac{75}{8}\)
\(12\frac{7}{10}=\frac{127}{10}\)
2\(\frac{3}{5}\)= \(\frac{2x5+3}{5}\)= \(\frac{13}{5}\)
5\(\frac{4}{9}\)= \(\frac{5x9+4}{9}\)= \(\frac{49}{9}\)
9\(\frac{3}{8}\)= \(\frac{9x8+3}{8}\)= \(\frac{75}{8}\)
12\(\frac{7}{10}\)= \(\frac{12x10+7}{10}\)= \(\frac{127}{10}\)
