Tính hộ cái :
\(\frac{13}{15}.0,25.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
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= \(\frac{13}{25}.0,25.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
\(A=\left(\frac{-2}{3}+1\frac{1}{4}-\frac{1}{6}\right).\frac{-12}{5}\)
=\(\left(\frac{-8+15-2}{12}\right).\frac{-12}{5}\)\(=\frac{5}{12}.\frac{-12}{5}=-1\)

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 + \(\left(\frac{8}{15}-1\frac{19}{60}\right)\) : \(1\frac{23}{24}\)
\(A=-\frac{2}{3}+1\frac{1}{4}-\frac{1}{6}=-\frac{2}{3}+\frac{5}{4}-\frac{1}{6}=\frac{5}{12}\)
\(B=\frac{13}{15}\cdot0,25\cdot3+\left(\frac{8}{15}-1\frac{19}{60}\right)\div1\frac{23}{24}\)
\(B=\frac{13}{15}\cdot\frac{1}{4}\cdot3+\left(\frac{8}{15}-\frac{79}{60}\right)\div\frac{47}{24}\)
\(B=\frac{13}{20}-\frac{47}{60}\cdot\frac{24}{47}\)
\(B=\frac{13}{20}-\frac{2}{5}=\frac{1}{4}\)
\(1\frac{13}{15}.\left(0,5\right)^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
\(1\frac{13}{15}.\left(0,5\right)^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
\(1\frac{13}{15}.\left(0,5\right)^2.3+\left(\frac{8}{15}-1\frac{19}{60}\right):1\frac{23}{24}\)
\(=1\frac{13}{15}.0,25.3+\left(-\frac{47}{60}\right):1\frac{23}{24}\)
\(=1\frac{13}{14}.0,75+\left(-\frac{2}{5}\right)\)
\(=1,4-0,4\)
\(=1\)
