Chuyển các hỗn số sau thành phân số:
2 $\frac{1}{3}$; 4 $\frac{2}{5}$; 3 $\frac{1}{4}$; 9 $\frac{5}{7}$; 10 $\frac{3}{10}$
Bài Làm:
2 $\frac{1}{3}$ = $\frac{6}{3}$ + $\frac{1}{3}$ = $\frac{7}{3}$
4 $\frac{2}{5}$ = $\frac{20}{5}$ + $\frac{2}{5}$ = $\frac{22}{5}$
3 $\frac{1}{4}$ = $\frac{12}{4}$ + $\frac{1}{4}$ = $\frac{13}{4}$
9 $\frac{5}{7}$ = $\frac{63}{7}$ + $\frac{5}{7}$ = $\frac{68}{7}$
10 $\frac{3}{10}$ = $\frac{100}{10}$ + $\frac{3}{10}$ = $\frac{103}{10}$
