Tính giá trị biểu thức:
3) C= \(\frac{5}{18}+\frac{8}{19}-\frac{7}{21}+\left(\frac{-10}{36}+\frac{11}{19}+\frac{1}{3}\right)-\frac{5}{8}\)\(\frac{5}{8}\)
4) D= \(\frac{1}{9}-\left|\frac{-5}{23}\right|-\left(\frac{-5}{23}+\frac{1}{9}+\frac{25}{7}\right)+\frac{50}{4}-\frac{7}{30}\)
bài 1: thực hiện pép tính:
1) \(5\frac{27}{5}+\frac{27}{23}+0,5-\frac{5}{27}+\frac{16}{23}\) 2) \(\frac{3}{8}.27\frac{1}{5}-\frac{5}{27}-51\frac{1}{5}.\frac{3}{8}+19\)
3)
Tính:
a) 51\(\frac{1}{5}\) . \(\frac{3}{8}\) + 27\(\frac{1}{5}\) . \(\frac{-3}{8}\) +19
b) \(\frac{1}{6}\) . (-2 \(\frac{3}{5}\)) + 1\(\frac{2}{3}\) . (\(\frac{-13}{5}\))
1/Tính
a) \(\left(\frac{7}{2}+\frac{17}{3}\right).\frac{8}{19}-\left(\frac{5}{2}+\frac{14}{3}\right).\frac{8}{19}\)
b)\(\frac{3^{2014}.8^{19}}{6^{60}.3^{1955}}\)
\(\left(1\frac{1}{3}+2\frac{3}{5}\right):\frac{8}{19}+\left(\frac{2}{3}-\frac{3}{5}\right):\frac{8}{19}\)
