Answer 2

1. a)

$\frac{11}{13} + \frac{19}{13}$

$\frac{11 + 19}{13}$

$\frac{30}{13}$

b)

$\frac{17}{15} + \frac{18}{15}$

$\frac{17 + 18}{15}$

$\frac{35}{15}$

$\frac{7}{3}$

c)

$\frac{17}{10} + \frac{33}{30}$

$\frac{17}{10} + \frac{11}{10}$

$\frac{17 + 11}{10}$

$\frac{28}{10}$

$\frac{14}{5}$

2.

a)

$\frac{5}{6} + 1 \frac{5}{12}$

$\frac{5}{6} + \frac{17}{12}$

$\frac{9}{4}$

b)

$2 \frac{9}{10} + \frac{4}{15}$

$\frac{29}{10} + \frac{4}{15}$

$\frac{19}{6}$

c)

$1 \frac{1}{6} + 2 \frac{2}{12}$

$(1 + 2) + ( \frac{1}{6} + \frac{2}{12})$

$3 + \frac{1}{3}$

$3 \frac{1}{3}$
