Tính:
a) A= \(\left(\frac{-2}{3}+1\frac{1}{4}-\frac{1}{6}\right).\frac{-12}{5}\)
b) B= \(\frac{13}{25}.0,25.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
Thực hiện phép tính sau :
A = \(\left(\frac{-2}{3}+1\frac{1}{4}-\frac{1}{6}\right)\)
B = \(\frac{13}{15}\).0,25.3 + \(\left(\frac{8}{15}-1\frac{19}{60}\right)\) : \(1\frac{23}{24}\)
giúp mình vs :
