Giải VBT Toán lớp 4 Bài 63: Phép nhân phân số

a) $\frac{2}{3} \times \frac{7}{10} = \frac{2 \times 7}{3 \times 10} = \frac{14}{30} = \frac{7}{15}$

c) $\frac{3}{8} \times \frac{3}{4} = \frac{3 \times 3}{8 \times 4} = \frac{9}{32}$

b) $\frac{1}{2} \times \frac{5}{6} = \frac{1 \times 5}{2 \times 6} = \frac{5}{12}$

d) $\frac{1}{5} \times \frac{10}{7} = \frac{1 \times 10}{5 \times 7} = \frac{10}{35} = \frac{2}{7}$
