Tính nhanh :
a) A = \(\dfrac{10\dfrac{1}{3}\left(26\dfrac{1}{3}-\dfrac{176}{7}\right)-\dfrac{12}{11}\left(\dfrac{10}{3}-1.75\right)}{\dfrac{5}{\left(91-0.25\right).\dfrac{60}{11}-1}}\)
b) ( 18.123+9.436.2+3.5310.6):(1+4+7+......+100-410)
tính A= 10\(\frac{1}{3}\)(26\(\frac{1}{7}\).\(\frac{176}{7}\))-\(\frac{12}{11}\)(\(\frac{10}{3}\)-1.75) /(\(\frac{5}{91}\)-0.25).\(\frac{60}{11}\)-1
\(A=\frac{10\frac{1}{3}.\left(26\frac{1}{3}-\frac{176}{7}\right)-\frac{12}{11}.\left(\frac{10}{3}-1.75\right)}{\frac{5}{\left(91-0,25\right).\frac{60}{11}-1}}\)

mk ko viết lại đề đâu
A=\(\frac{\frac{31}{3}.\frac{25}{21}-\frac{12}{11}.\frac{19}{12}}{\frac{5}{90,75.\frac{60}{11}-1}}=\frac{\frac{775}{63}-\frac{19}{11}}{\frac{5}{495-1}}=\frac{7328}{693}:\frac{5}{494}=\frac{7328}{693}.\frac{494}{5}=\)
có máy tính thì tính được hết

\(=\dfrac{\dfrac{31}{3}\cdot\left(26+\dfrac{1}{3}-\dfrac{176}{7}\right)-\dfrac{12}{11}\cdot\left(\dfrac{10}{3}-\dfrac{7}{4}\right)}{\left(\dfrac{5}{90.75}\right)\cdot\dfrac{60}{11}-1}\)
\(=\dfrac{\dfrac{31}{3}\cdot\dfrac{25}{21}-\dfrac{12}{11}\cdot\dfrac{19}{12}}{-\dfrac{931}{1331}}\)
\(=\dfrac{7328}{693}:\dfrac{-931}{1331}\simeq-15.118\)
