làm nhanh lên nhé vì mai mình nộp rồi
\(\frac{4}{7}.\frac{3}{5}.\frac{7}{4}.\left(-20\right).\frac{-11}{12}\)Tính nhazz
\(\frac{7}{13}.\frac{5}{19}+\frac{7}{19}.\frac{8}{13}-\frac{37}{19}\)
Bai 1: a) \(\frac{3}{7}.\frac{-5}{9}+\frac{4}{9}.\frac{3}{7}-\frac{3}{7}.\frac{8}{9}\)
b) \(1\frac{13}{15}.0,75-\left(\frac{11}{20}+25\%\right):\frac{7}{5}\)
bài 2:
a) \(\frac{-3}{4}x-\frac{4}{10}=\frac{1}{5}\)
b) \(3\left(x-\frac{1}{3}\right)+\frac{1}{3}x=\frac{1}{19}:\frac{12}{19}\)
c)
\(D = \frac{8}{19} . \frac{5}{11} + \frac{7}{11}. \frac {8}{19} - \frac{8}{9} . \frac{1}{11}\)
