\(\left(\frac{4}{3}-\frac{2}{3}-\frac{9}{8}\right):\left(1-\frac{4}{5}\right)\)
\(=\left(\frac{2}{3}-\frac{9}{8}\right):\left(1-\frac{4}{5}\right)\)
\(=-\frac{11}{24}:\frac{1}{5}\)
\(=-\frac{55}{24}\)
(4/3-2/3-9/8):(1-4/5)
=-11/24:1/5
=-79/120
k cho mk nhé,bn hok tốt
\(\left(\frac{4}{3}-\frac{2}{3}-\frac{9}{8}\right)\div\left(1-\frac{4}{5}\right)\)
\(\left(\frac{2}{3}-\frac{9}{8}\right)\div\left(\frac{5}{5}-\frac{4}{5}\right)\)
\(\left(\frac{16}{24}-\frac{27}{24}\right)\div\frac{1}{5}\)
\(\frac{-11}{24}\div\frac{1}{5}\)
\(-\frac{11}{24}\times5\)
\(-\frac{55}{24}\)
\(\left(\frac{4}{3}-\frac{2}{3}-\frac{9}{8}\right):\left(1-\frac{4}{5}\right)\)
= \(\left(\frac{32}{24}-\frac{16}{24}-\frac{27}{24}\right):\left(\frac{5}{5}-\frac{4}{5}\right)\)
= \(\left(\frac{32-16-27}{24}\right).\frac{5}{1}\)
= \(\frac{-11}{24}.5\)
= \(\frac{-55}{24}\)
