\(\frac{4-\frac{1}{23}-\frac{56}{39}-\frac{25}{47}}{\frac{5}{69}+\frac{5}{117}+\frac{5}{141}}\)
Tính hợp lí :
\(B=\frac{4-\frac{1}{23}-\frac{56}{39}-\frac{25}{47}}{\frac{5}{69}+\frac{5}{117}+\frac{5}{141}}\)
1, Tính hợp lí:
A=\(\frac{4-\frac{1}{23}-\frac{56}{39}-\frac{25}{47}}{\frac{5}{69}+\frac{5}{117}+\frac{5}{141}}\)
Thực hiện phép tính (hợp lý nếu có thể): \(\frac{4-\frac{1}{23}-\frac{5}{39}-\frac{25}{47}}{\frac{5}{69}+\frac{5}{117}+\frac{5}{141}}.\)
Ai làm nhanh và đúng cho 3 tick.
Tính tổng, tích:
a)\(\frac{2}{2017}+\frac{2}{2018}\)phần\(\frac{5}{2017}+\frac{5}{2018}\)( xin lỗi vì mình ko ghi kí hiệu được)
b) B=(\(\frac{64}{128}\)+\(\frac{3}{4}\)):\(1\frac{3}{16}\)phần \(1\frac{11}{19}\)
c)\(\frac{2181.729+240.81+27}{^{3^2.9^2.234+18.54.162.9+723.729}}\)
d) A=(\(2\frac{1}{4}-5\frac{5}{9}\)).\(2\frac{2}{17}\)phần 6,75+\(\frac{1}{12}+3\frac{1}{6}\)-\(\frac{5}{12}\)(\(\frac{4}{5}-\frac{1}{10}\)):\(\frac{-5}{24}\)
e) 4-\(\frac{1}{23}-\frac{56}{39}-\frac{25}{47}\)phần \(\frac{5}{69}+\frac{5}{117}+\frac{5}{141}\)
HELP ME!
Tính A = \(3.\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5.\frac{118}{119}-\frac{5}{117}.\frac{1}{119}+\frac{8}{39}\)
tính:
D=\(3\frac{1}{117}.\frac{1}{119}-\frac{4}{117}.5\frac{118}{119}-\frac{5}{117.118}+\frac{8}{39}\)
a) \(\frac{21}{47}+\frac{9}{45}+\frac{26}{45}+\frac{4}{5}\) ; b) \(\frac{15}{12}+\frac{5}{13}-\frac{3}{12}-\frac{18}{13}\)
c) \(\frac{27}{23}+\frac{5}{21}-\frac{4}{23}+\frac{6}{21}+\frac{1}{2}\) ; d) \(\frac{13}{25}+\frac{6}{41}-\frac{38}{25}+\frac{35}{41}-\frac{1}{2}\)
(like)
Cho A = \(\frac{\left(3\frac{2}{5}+\frac{1}{5}\right):2\frac{1}{2}}{\left(5\frac{3}{7}-2\frac{1}{4}\right):4\frac{43}{56}}\); B = \(\frac{1,2:\left(1\frac{1}{5}-1\frac{1}{4}\right)}{0,32+\frac{2}{25}}\)
So sánh A và B
