\(\frac{5}{7}=\frac{1}{7}+\frac{4}{7}=\frac{2}{7}+\frac{5}{7}=\frac{3}{7}+\frac{4}{7}=....\)
\(\frac{13}{27}=\frac{10}{27}+\frac{1}{9}\)
a) \(\frac{5}{7}=\frac{1}{7}+\frac{4}{7}\) hoặc \(\frac{5}{7}=\frac{2}{7}+\frac{3}{7}\)
b) \(\frac{13}{27}=\frac{2}{27}+\frac{11}{27}\) hoặc \(\frac{13}{27}=\frac{5}{27}+\frac{8}{27}\)
Chúc bạn học giỏi và tíck cho mìk vs nhá!
\(\frac{5}{7}=\frac{1}{7}+\frac{4}{7}\)
\(\frac{13}{27}=\frac{10}{27}+\frac{1}{9}\)
