Question

Rút gọn các phân số sau đây :

\(\frac{48}{96};\frac{42}{98};\frac{80}{240};\frac{75}{100};\frac{64}{720};\frac{15}{120}.\)

Answer 1

\(\frac{48}{96}=\frac{48:48}{96:48}=\frac{1}{2}\)

\(\frac{42}{98}=\frac{42:14}{98:14}=\frac{3}{7}\)

\(\frac{80}{240}=\frac{80:80}{240:80}=\frac{1}{3}\)

\(\frac{75}{100}=\frac{75:25}{100:25}=\frac{3}{4}\)

\(\frac{64}{720}=\frac{64:16}{720:16}=\frac{4}{45}\)

\(\frac{15}{120}=\frac{15:15}{120:15}=\frac{1}{8}\)
