\(=\frac{3}{20}\left(44-26\right)=\frac{3}{20}\cdot18=\frac{27}{10}\)
Bài làm
\(-\frac{3}{4}.26\frac{1}{5}+\frac{3}{4}.44\frac{1}{5}\)
\(=\frac{3}{4}.\left(-\frac{131}{5}\right)+\frac{3}{4}.\left(\frac{221}{5}\right)\)
\(=\frac{3}{4}.\left(-\frac{131}{5}+\frac{221}{5}\right)\)
\(=\frac{3}{4}.\frac{90}{5}\)
\(=\frac{3}{2}.18\)
\(=27\)
# Học tốt #
\(-\frac{3}{4}.26\frac{1}{5}+\frac{3}{4}.44\frac{1}{5}\)
= \(\frac{3}{4}.-\frac{131}{5}+\frac{3}{4}.\frac{221}{5}\)
= \(\frac{3}{4}.\left(-\frac{131}{5}+\frac{221}{5}\right)\)
= \(\frac{3}{4}.\frac{90}{5}\)
= \(\frac{27}{2}\)
Chúc bạn học tốt !!!
\(\frac{-3}{4}.26\frac{1}{5}+\frac{3}{4}.44\frac{1}{5}\)
\(=\frac{-3}{4}.26\frac{1}{5}+\frac{-3}{4}.\left(-44\frac{1}{5}\right)\)
\(=\frac{-3}{4}\left[26\frac{1}{5}+\left(-44\frac{1}{5}\right)\right]\)
\(=\frac{-3}{4}.\left(-18\right)\)
\(=\frac{\left(-3\right).\left(-18\right)}{4}=\frac{27}{2}\)
