Question

Chuyển hỗn số thành phân số:

2\(\frac{3}{5}\),      5 \(\frac{4}{9}\)               \(9\frac{3}{8}\)\(12\frac{7}{10}\)

Chỗ 12 7/10 cách 9 3/8 đó

Answer 1

\(2\frac{3}{5}=\frac{2x5+3}{5}=\frac{10+3}{5}=\frac{13}{5}\)

\(5\frac{4}{9}=\frac{5x9+4}{9}=\frac{45+4}{9}=\frac{49}{9}\)

\(9\frac{3}{8}=\frac{9x8+3}{8}=\frac{72+3}{8}=\frac{75}{8}\)

\(12\frac{7}{10}=\frac{12x10+7}{10}=\frac{120+7}{10}=\frac{127}{10}\)

Answer 2

\(2\frac{3}{5}=\frac{13}{5}\)

\(5\frac{4}{9}=\frac{49}{9}\)

\(9\frac{3}{8}=\frac{75}{8}\)

\(12\frac{7}{10}=\frac{127}{10}\)

Answer 3

2 3/5 =13/5

5 4/9=49/9

9 3/8=75/8

12 7/10=127/10
