b] \(\frac{127}{-128}>-1\)\(;\)\(\frac{-1345}{1244}< -1\)
\(\Rightarrow\frac{127}{-128}>-1>\frac{-1345}{1244}\Rightarrow\frac{127}{-128}>\frac{-1345}{1244}\)
c]\(\frac{-11}{33}=\frac{-1}{3}\)\(;\)\(\frac{25}{-76}>\frac{25}{-75}=\frac{-1}{3}\)\(\Rightarrow\frac{-11}{33}=\frac{-1}{3}< \frac{25}{-76}\Rightarrow\frac{-11}{33}< \frac{25}{-76}\)
d] \(\frac{-171717}{232323}=\frac{-17\times10101}{23\times10101}=\frac{-17}{23}\)\(\Rightarrow\frac{-17}{23}=\frac{-171717}{232323}\)
\(\frac{-17}{31}\)=\(\frac{-17.101}{31.101}\)= \(\frac{-1717}{3131}\)
=> \(\frac{-17}{31}\)=\(\frac{-1717}{3131}\)
a)\(\frac{19}{-20}>\frac{19}{21}\)
\(\frac{-17}{21}< \frac{19}{21}\)
\(\Rightarrow\frac{19}{-20}>\frac{-17}{21}\)
b tương tự
a) \(\frac{325}{260}=\frac{650}{520}< \frac{650}{320}< \frac{876}{320}\)
\(\Rightarrow\frac{325}{260}< \frac{876}{320}.\)
b) \(\frac{13}{9}< \frac{24}{9}=\frac{8}{3}\)
\(\Rightarrow\frac{13}{9}< \frac{8}{3}.\)
c) Do \(18>-17;-39< 41\)
\(\Rightarrow\frac{18}{-39}>\frac{-17}{41}.\)
d) \(\frac{-151515}{232323}=\frac{\left(-15\right).10101}{23.10101}=\frac{-15}{23}\)
Mà \(\frac{-15}{25}< \frac{-15}{23}\)
\(\Rightarrow\frac{-15}{25}< \frac{-151515}{232323}.\)
\(\text{a)}\frac{-1}{5}< 0< \frac{1}{1000}\Rightarrow\frac{-1}{5}< \frac{1}{1000}\)
\(\text{b)}\frac{-267}{268}>-1>\frac{-1347}{1343}\Rightarrow\frac{267}{268}>\frac{-1347}{1343}\)
\(\text{c)}\frac{-13}{38}>\frac{-13}{39}=\frac{-1}{3}=\frac{29}{-87}>\frac{29}{-88}\Rightarrow\frac{-13}{38}>\frac{29}{-88}\)
\(\text{d)}\frac{-18}{31}=\frac{\left(-18\right).10101}{31.10101}=\frac{-181818}{313131}\Rightarrow\frac{-18}{31}=\frac{-181818}{313131}\)
