$a) \: 1 + \frac{2}{3} = \frac{1(3}{1(3} + \frac{2(1}{3(1} = \frac{3 + 2}{3} = \frac{5}{3}$

$b) \: \frac{7}{10} + 1 = \frac{7(1}{10(1} + \frac{1(10}{1(10} = \frac{7 + 10}{10} = \frac{17}{10}$

$c) \: 2 + \frac{2}{3} = \frac{2(3}{1(3} + \frac{2(1}{3(1} = \frac{6 + 2}{3} = \frac{8}{3}$

$d) \: \frac{1}{10} + 2 = \frac{1(1}{10(1} + \frac{2(10}{1(10} = \frac{1 + 20}{10} = \frac{21}{10}$
