Answer 1

a) $\frac{13}{2} - \frac{11}{3} + \frac{1}{3}$

$= \frac{39 - 22 + 2}{6}$

$= \frac{19}{6}$

b) $\frac{5}{18} + \frac{4}{9} - \frac{2}{3}$

$=$ $\frac{5 + 8 - 12}{18}$

$= \frac{1}{18}$

c) $\frac{1}{2} + \frac{5}{6} + \frac{7}{6}$

$= \frac{6 + 10 + 14}{12}$

$= \frac{30}{12} :2 = \frac{15}{6} :3=\frac{5}{2}$

d) $\frac{6}{7} - \frac{3}{8} + \frac{1}{4}$

$= \frac{48 - 21 + 14}{56}$

$= \frac{41}{56}$
