Answer 1

\(\frac{50}{150}=\frac{1}{3}\)

\(\frac{5}{20}=\frac{1}{4}\)

\(\frac{8}{32}=\frac{1}{4}\)

Sau đó bạn cứ rút gọn thôi,tích cho tớ nha

Answer 2

\(\frac{1}{3}\)\(\frac{1}{4}\)\(\frac{1}{4}\)\(\frac{2}{3}\)\(\frac{2}{3}\)\(\frac{3}{2}\)\(\frac{3}{5}\)\(\frac{1}{2}\)\(\frac{18}{5}\)\(\frac{1}{4}\)\(\frac{1}{25}\)\(\frac{1}{8}\)\(\frac{1}{2}\)\(\frac{3}{7}\)\(\frac{2}{3}\)\(\frac{1}{3}\)k cho mk nha

Answer 3

\(\dfrac{50}{150}\) = \(\dfrac{50:50}{150:50}\) = \(\dfrac{1}{3}\)         \(\dfrac{8}{32}\) = \(\dfrac{8:8}{32:8}\) = \(\dfrac{1}{4}\)

\(\dfrac{5}{20}\) = \(\dfrac{5:5}{20:5}\) = \(\dfrac{1}{4}\)                 \(\dfrac{8}{12}\) = \(\dfrac{8:4}{12:4}\) = \(\dfrac{2}{3}\)

Answer 4

\(\dfrac{4}{6}\) = \(\dfrac{4:2}{6:2}=\dfrac{2}{3}\)                     \(\dfrac{12}{8}=\dfrac{12:4}{8:4}\) = \(\dfrac{3}{2}\)

\(\dfrac{15}{25}\) = \(\dfrac{15:5}{25:5}\) = \(\dfrac{3}{5}\)                   \(\dfrac{11}{22}\) = \(\dfrac{11:11}{22:11}\) = \(\dfrac{1}{2}\)

Answer 5

\(\dfrac{36}{10}=\dfrac{36:2}{10:2}\) = \(\dfrac{18}{5}\)                \(\dfrac{75}{300}\) = \(\dfrac{75:75}{300:75}\) = \(\dfrac{1}{4}\)

\(\dfrac{4}{100}\) = \(\dfrac{4:4}{100:4}\) = \(\dfrac{1}{25}\)             \(\dfrac{9}{72}\) = \(\dfrac{9:9}{72:9}\) = \(\dfrac{1}{8}\)

 

Answer 6

\(\dfrac{5}{10}\) = \(\dfrac{5:5}{10:5}\) = \(\dfrac{1}{2}\)                     \(\dfrac{15}{35}\) = \(\dfrac{15:5}{35:5}=\dfrac{3}{7}\)

\(\dfrac{10}{15}\) = \(\dfrac{10:5}{15:5}\) = \(\dfrac{2}{3}\)                     \(\dfrac{9}{27}\) = \(\dfrac{9:9}{27:9}\) = \(\dfrac{1}{3}\)
