Question

Giúp mik nhé!!

\(\left(9\frac{2}{4}:5,2+3,4\cdot2\frac{7}{34}\right):\left(-1\frac{9}{16}\right)\)

Answer 1

\(\left(9\frac{2}{4}:5,2+3,4.2\frac{7}{34}\right):\left(-1\frac{9}{16}\right)\)

\(=\left(\frac{19}{2}:\frac{26}{5}+\frac{17}{5}.\frac{75}{34}\right):\left(\frac{-25}{16}\right)\)

\(=\left(\frac{19}{2}.\frac{5}{26}+\frac{17}{5}.\frac{75}{34}\right):\left(-\frac{25}{16}\right)\)

\(=\left(\frac{95}{52}+\frac{15}{2}\right).\frac{-16}{25}\)

\(=\frac{485}{52}.\left(-\frac{16}{25}\right)\)

\(=-\frac{388}{65}\)

(Bài này kết quả lớn ghê :))

Answer 2

Kết quả là -388/65
