Rút gọn:
\(\frac{18}{30}=\frac{18:6}{30:6}=\frac{3}{5}\)
\(\frac{36}{27}=\frac{36:9}{27:9}=\frac{4}{3}\)
\(\frac{64}{80}=\frac{64:16}{80:16}=\frac{4}{5}\)
\(\frac{45}{35}=\frac{45:5}{35:5}=\frac{9}{7}\)
Rút gọn các phân số sau :
\(\frac{18}{30}=\frac{18\div6}{30\div6}=\frac{3}{5}\)
\(\frac{64}{80}=\frac{64\div16}{80\div16}=\frac{4}{5}\)
\(\frac{36}{27}=\frac{36\div9}{27\div9}=\frac{4}{3}\)
\(\frac{45}{35}=\frac{45\div5}{35\div5}=\frac{9}{7}\)
\(\frac{48}{64}\)= \(\frac{24}{32}\)= \(\frac{12}{16}\)= \(\frac{6}{8}\)=\(\frac{3}{4}\)
\(\frac{48}{64}\)=\(\frac{3}{4}\) ủng hộ mk nha!!! ##@@.vn
\(\frac{90}{100}=\frac{90:10}{100:10}=\frac{9}{10}\)
\(\frac{64}{128}=\frac{64:64}{128:64}=\frac{1}{2}\)
\(\frac{17}{51}=\frac{17:17}{51:17}=\frac{1}{3}\)
\(\frac{152}{608}=\frac{152:152}{608:152}=\frac{1}{4}\)
\(\frac{63}{315}=\frac{63:63}{315:63}=\frac{1}{5}\)
\(\frac{75}{36}=\frac{75\div3}{36\div3}=\frac{25}{12}\)
😘😘😘
~~~học tốt nhé~~~
\(\frac{48}{96}=\frac{48:48}{96:48}=\frac{1}{2}\)
\(\frac{42}{98}=\frac{42:14}{98:14}=\frac{3}{7}\)
\(\frac{80}{240}=\frac{80:80}{240:80}=\frac{1}{3}\)
\(\frac{75}{100}=\frac{75:25}{100:25}=\frac{3}{4}\)
\(\frac{64}{720}=\frac{64:16}{720:16}=\frac{4}{45}\)
\(\frac{15}{120}=\frac{15:15}{120:15}=\frac{1}{8}\)
48/96=1/2
42/98=3/7
80/240=1/3
75/100=3/4
64/720=4/45
15/120=1/8
ta có:
\(\frac{36}{64}=\frac{36:4}{64:4}=\frac{9}{16}\)
nha
\(\frac{36}{64}=\frac{9}{16}\)
