thục hiện dãy tính :
\(\frac{\frac{3}{67}.\left(17\frac{21}{56}-13\frac{21}{45}\right):\left(\frac{3}{5.22}+\frac{54}{44.65}+\frac{18}{65.72}\right)}{29^3:100-29^3:0,47}\)
help me
Tính:
\(\frac{\frac{3}{67}\left(17\frac{21}{56}-22\frac{7}{12}\right).\left(\frac{3}{5.22}+\frac{54}{44.65}+\frac{18}{65.72}\right)}{29^3:100-29^3:0.47}\)
1) Tính hợp lýa)frac{31}{23}-left(frac{7}{32}+frac{8}{32}right)b)left(frac{1}{3}+frac{12}{67}+frac{13}{41}right)-left(frac{79}{67}-frac{28}{41}right)c)frac{38}{45}-left(frac{8}{45}-frac{17}{51}-frac{3}{11}right)d)left(frac{17}{28}+frac{18}{29}-frac{19}{30}-frac{30}{31}right).left(-frac{5}{12}+frac{1}{4}+frac{1}{6}right)

1) Tính hợp lý
a)\(\frac{31}{23}-\left(\frac{7}{32}+\frac{8}{32}\right)\)
b)\(\left(\frac{1}{3}+\frac{12}{67}+\frac{13}{41}\right)-\left(\frac{79}{67}-\frac{28}{41}\right)\)
c)\(\frac{38}{45}-\left(\frac{8}{45}-\frac{17}{51}-\frac{3}{11}\right)\)
d)\(\left(\frac{17}{28}+\frac{18}{29}-\frac{19}{30}-\frac{30}{31}\right).\left(-\frac{5}{12}+\frac{1}{4}+\frac{1}{6}\right)\)
\(\frac{3}{5.22}+\frac{54}{44.65}+\frac{18}{65.72}\)
\(\frac{3}{5.22}+\frac{54}{44.65}+\frac{18}{65.72}\)
\(\frac{3}{5.22}+\frac{54}{44.65}+\frac{18}{65.72}\)
\(\frac{3}{67}\left(17\frac{21}{45}-13\frac{21}{45}\right)\)
Tính bằng cách hợp lý nhất:
a, \(\frac{31}{23}-\left(\frac{7}{32}+\frac{8}{23}\right)\)
b, \(\left(\frac{1}{3}+\frac{12}{67}+\frac{13}{41}\right)-\left(\frac{79}{67}-\frac{28}{41}\right)\)
c, \(\frac{38}{45}-\left(\frac{8}{45}-\frac{17}{51}-\frac{3}{11}\right)\)
