- \(\frac{3}{5}:\frac{3}{7}=\frac{3}{5}x\frac{7}{3}=\frac{21}{15}=\frac{7}{5}\)
- \(\frac{3}{7}x\frac{8}{5}-\frac{16}{35}\)
= \(\frac{24}{35}-\frac{16}{35}\)
= \(\frac{8}{35}\)
# Chúc bạn học tốt #
\(\frac{3}{5}:\frac{3}{7}=\frac{3}{5}\times\frac{7}{3}=\frac{3\times7}{5\times3}=\frac{1\times7}{5\times1}=\frac{7}{5}\)
\(\frac{3}{7}\times\frac{8}{5}-\frac{16}{35}=\frac{3\times8}{7\times5}-\frac{16}{35}=\frac{24}{35}-\frac{16}{35}=\frac{8}{35}\)
\(\frac{3}{5}:\frac{3}{7}=\frac{7}{5}\)
\(\frac{3}{7}\)x \(\frac{8}{5}\)- \(\frac{16}{35}\)= \(\frac{24}{35}-\frac{16}{35}=\frac{8}{35}\)
