a) \(\frac{1}{2}\),\(\frac{-2}{3}\),\(\frac{3}{4}\),\(\frac{-4}{5}\)
b) \(\frac{1}{2}\),\(\frac{3}{5}\),\(\frac{-4}{3}\),\(\frac{-9}{8}\)
c) \(\frac{3}{2}\),\(\frac{3}{4}\),\(\frac{4}{5}\)\(\frac{-7}{20}\)
d) \(\frac{1}{2}\),\(\frac{-2}{3}\)\(\frac{5}{6}\),\(\frac{-7}{18}\)
Cau 2:
[6+\(\left(\frac{1}{2}\right)^3\)_\(\left|-\frac{1}{2}\right|\)]:\(\frac{3}{12}\)
\(\frac{18}{37}\)+\(\frac{8}{24}\)+\(\frac{19}{37}\)_\(1\frac{23}{24}\)+\(\frac{2}{3}\)
lm giup mk nhe mk minh se tick cho bn cam on
\(\left(6+\left(\frac{1}{2}\right)^3-\left|-\frac{1}{2}\right|\right):\frac{3}{12}\)
\(=\left(6+\frac{1}{8}+\frac{1}{2}\right):\frac{1}{4}\)
=\(\frac{53}{8}:\frac{1}{4}\)
\(=\frac{53}{2}\)
a)30/60,-40/60,45/60,48/60
45/60>30/60>-40/60>-48/60
=3/4>1/2>-2/3>-4/5
