[Nguyễn Thị Thương Hoài]

  \(\dfrac{37}{4}+\dfrac{44}{7}\) + \(\dfrac{38}{5}\) + \(\dfrac{26}{3}\) + \(\dfrac{1}{3}\) + \(\dfrac{5}{7}\) + \(\dfrac{3}{4}\)

= ( \(\dfrac{37}{4}+\) \(\dfrac{3}{4}\)) + ( \(\dfrac{26}{3}+\dfrac{1}{3}\)) + (\(\dfrac{44}{7}+\dfrac{5}{7}\)) + \(\dfrac{38}{5}\)

= \(\dfrac{40}{4}\) + \(\dfrac{27}{3}\) + \(\dfrac{49}{7}\) + \(\dfrac{38}{5}\)

= 10 + 9 + 7 + \(\dfrac{38}{5}\)

=26 + 7,6

= 33,6
