Answer 1

[Không Tên]

\(\frac{49}{3}+\frac{33}{5}+\frac{25}{7}+\frac{26}{3}+\frac{17}{7}+\frac{27}{5}\)

\(=\left(\frac{49}{3}+\frac{26}{3}\right)+\left(\frac{33}{5}+\frac{27}{5}\right)+\left(\frac{25}{7}+\frac{17}{7}\right)\)

\(=\frac{75}{3}+\frac{60}{5}+\frac{42}{7}\)

\(=15+12+6=33\)

Answer 2

[Trần Lê Tiến Dũng]

(49/3+26/3)+(33/5+27/5)+(25/7+17/7)

12              +         6          +       25

= 43
