\(\frac{9}{8}>\frac{8}{9}\)
\(\frac{16}{23}>\frac{16}{25}\)
\(\frac{8}{11}< \frac{8}{10}\)
\(\frac{10}{13}>\frac{19}{26}\)
\(\frac{13}{15}< \frac{11}{10}\)
\(\frac{11}{9}=\frac{44}{36}\)
9/8 > 8/9
16/23 > 16/25
8/11 < 8/10
10/13 > 19/26
13/15 < 11/10
11/9 = 44/36

Chúc bạn học giỏi !
\(\frac{5}{6}:\frac{8}{9}-\frac{3}{4}:\frac{8}{9}\)
\(=\left(\frac{5}{6}-\frac{3}{4}\right):\frac{8}{9}\)
\(=\frac{1}{12}:\frac{8}{9}\)
\(=\frac{1}{12}\times\frac{9}{8}\)
\(=\frac{3}{32}\)
(\(\frac{5}{6}\)-\(\frac{3}{4}\)) : \(\frac{8}{9}\)
=\(\frac{1}{12}\): \(\frac{8}{9}\)
=\(\frac{3}{32}\)
k nhé, sau đó kb lun!
\(\frac{1}{2}+\frac{1}{2}=\frac{1+1}{2}=\frac{2}{2}=1\)
\(\frac{3}{4}+\frac{1}{4}=\frac{3+1}{4}=\frac{4}{4}=1\)
\(\frac{3}{9}+\frac{6}{9}=\frac{3+6}{9}=\frac{9}{9}=1\)
12/14 + 15/20 + 6/7 + 3/4
= ( 12/14 + 6/7 ) + ( 15/20 + 3/4 )
= ( 6/7 + 6/7 ) + ( 3/4 + 3/4 )
= 12/7 + 6/4
= 48/28 + 42/28
= 90/28
= 45/14

\(\frac{7}{8}\)x \(\frac{8}{9}\)x \(\frac{9}{10}\)
= \(\frac{7}{9}\)x \(\frac{9}{10}\)
= \(\frac{7}{10}\)
1 x \(\frac{2}{3}\): \(\frac{4}{3}\) : \(\frac{5}{4}\)
= \(\frac{2}{3}\)x \(\frac{3}{4}\)x \(\frac{4}{5}\)
= \(\frac{1}{2}\) x \(\frac{4}{5}\)
= \(\frac{2}{5}\)
\(\frac{7}{8}\times\frac{8}{9}\times\frac{9}{10}\)
\(=\frac{7\times8\times9}{8\times9\times10}\)
\(=\frac{7}{10}\)
\(1\times\frac{2}{3}:\frac{4}{3}:\frac{5}{4}\)
\(=\frac{2}{3}\times\frac{3}{4}\times\frac{4}{5}\)
\(=\frac{2}{5}\)
\(\frac{12}{20}\)= \(\frac{6}{10}\)= \(\frac{3}{5}\)
\(\frac{3}{4}\)= \(\frac{9}{12}\)= \(\frac{12}{16}\)= \(\frac{15}{20}\)
\(\frac{75}{45}\)= \(\frac{15}{9}\)= \(\frac{5}{3}\)
\(\frac{3}{4}\)= \(\frac{18}{24}\)= \(\frac{12}{16}\)
12/20 = 6/10 = 3/5
3/4 = 9/12 = 12/16 = 15/20
75/45 = 15/9 = 5/3
3/4 = 18/24 = 12/16
