~học tốt~
a 4/5
b 4/3
\(\frac{3}{5}\div\frac{3}{4}=\frac{3}{5}\times\frac{4}{3}=\frac{3\times4}{5\times3}=\frac{4}{5}.\)
\(\frac{2}{5}\div\frac{3}{10}=\frac{2}{5}\times\frac{10}{3}=\frac{2\times10}{5\times3}=\frac{2\times2\times5}{5\times3}=\frac{4}{3}\)
a) \(\frac{3}{5}\div\frac{3}{4}=\frac{3}{5}\times\frac{4}{3}=\frac{12}{5}\)
b) \(\frac{2}{5}\div\frac{3}{10}=\frac{2}{5}\times\frac{10}{3}=\frac{20}{15}=\frac{4}{3}\)
ufffffffffffffffffffffffffffffffff
thank you các bạn nha
