\(2\dfrac{3}{13}x\dfrac{27}{58}x2\dfrac{15}{24}x\dfrac{8}{21}:\dfrac{3}{7}\)
= \(\dfrac{29}{13}x\dfrac{27}{58}x\dfrac{63}{24}x\dfrac{8}{21}x\dfrac{7}{3}\)
= \(\dfrac{9x7}{13x2}=\dfrac{63}{26}\)
Giúp tui mọi người ơii, tui đang cần gấp ạ!
A = 2\(\dfrac{3}{13}\) \(\times\) \(\dfrac{27}{58}\) \(\times\) 2\(\dfrac{15}{24}\) \(\times\) \(\dfrac{8}{21}\):\(\dfrac{3}{7}\)
A = \(\dfrac{29}{13}\) \(\times\) \(\dfrac{27}{58}\) \(\times\) \(\dfrac{21}{8}\) \(\times\) \(\dfrac{8}{21}\) \(\times\) \(\dfrac{7}{3}\)
A = \(\dfrac{63}{26}\)
