\(\frac{6}{7}...\frac{7}{9}\)\(\frac{31}{32}...\frac{26}{25}\)\(\frac{2014}{4}...1\)
\(\frac{6}{7}\) > \(\frac{7}{9}\)
\(\frac{31}{32}\) < \(\frac{26}{25}\)
\(\frac{2014}{4}\) > 1
\(\frac{9}{8}>\frac{8}{9}\)
\(\frac{16}{23}>\frac{16}{25}\)
\(\frac{8}{11}< \frac{8}{10}\)
\(\frac{10}{13}>\frac{19}{26}\)
\(\frac{13}{15}< \frac{11}{10}\)
\(\frac{11}{9}=\frac{44}{36}\)
9/8 > 8/9
16/23 > 16/25
8/11 < 8/10
10/13 > 19/26
13/15 < 11/10
11/9 = 44/36
Tham khảo nha !
Chúc bạn học giỏi !
\(\frac{3}{5}>\frac{4}{7};\frac{2}{3}< \frac{3}{2}\)
k mik va kb lun nha
A 16X5X9X3X4/3X5X16X9X4=1/1=1
B 1996X1995-1996X1/1994X1+1995X1994
=1995X(1996-1)/1995X(1994+1)=1995X1995/1995X1995
=1/1=1
a) \(\frac{1}{2}+\frac{1}{4}< \frac{3}{4}+\frac{1}{5}\)
b) \(\frac{7}{13}+\frac{2}{9}>\frac{3}{26}+\frac{7}{13}\)
~ GHÉT ..............................~
a) \(\frac{1}{2}+\frac{1}{4}< \frac{3}{4}+\frac{1}{5}\)
b) \(\frac{7}{13}+\frac{2}{9}>\frac{3}{26}+\frac{7}{13}\)
dau < nhe
\(\frac{721}{218}....\frac{721}{215}\)
Vì 218 > 215 nên \(\frac{721}{218}< \frac{721}{215}\)
Ủng hộ nhé ! Bấm Đúng nếu thấy mình trả lời đúng !
