Question

Bài 1.Tính:

a)\((-\frac{1}{2})^3\div1\frac{3}{8}-75\%\times(-6\frac{2}{11})\)

Answer 1

\(\left(-\frac{1}{2}\right)^3:1\frac{3}{8}-75\%.\left(-6\frac{2}{11}\right)\)

\(=-\frac{1}{8}:\frac{11}{8}-\frac{3}{4}.\left(-\frac{68}{11}\right)\)

\(=-\frac{1}{8}\cdot\frac{8}{11}-\frac{3}{4}\cdot\frac{68}{11}\)

\(=-\frac{1}{11}-\frac{3.17}{11}=-\frac{52}{11}\)
