Tờ inh tinh sắc tính:
a) A= \(\left(\frac{-2}{3}+1\frac{1}{4}-\frac{1}{6}\right).\frac{-12}{5}\)
b) B= \(\frac{13}{15}.0,25.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
Tính:
a) A= \(\left(\frac{-2}{3}+1\frac{1}{4}-\frac{1}{6}\right).\frac{-12}{5}\)
b) B= \(\frac{13}{25}.0,25.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
\(A=\left(\frac{-2}{3}+1\frac{1}{4}-\frac{1}{6}\right).\frac{-12}{5}\)
=\(\left(\frac{-8+15-2}{12}\right).\frac{-12}{5}\)\(=\frac{5}{12}.\frac{-12}{5}=-1\)
