Môn Toán Lớp 6: 1 5/27(-3/2)^2 + (2,6- 1 3/15):(-3/8)

Giải đáp:

 1\frac{5}{27}.(-\frac{3}{2})^{2}+(2,6-1\frac{3}{15}):(-\frac{3}{8})

=\frac{32}{27}.\frac{9}{4}+(\frac{13}{5}-\frac{6}{5}).(-\frac{8}{3}

=(\frac{8.4.9}{9.3.4})+\frac{7}{5}.(-\frac{8}{3})

=\frac{8}{3}+\frac{-56}{15}

=\frac{40}{15}+\frac{-56}{15}

=\frac{-16}{15}
