Question

2) Calcule:

a) 1\3+2\5:

b) 7\2+2\3

Answer 1

$\frac{1}{3} + \frac{2}{5} = \frac{3}{8} \\ \\ \frac{7}{2} + \frac{2}{3} = \frac{9}{5}$

Answer 2

$a) \\ \frac{1}{3} + \frac{2}{5} \\ \frac{5}{15} + \frac{6}{15} \\ \frac{11}{15} \\ \\ b) \\ \frac{7}{2} + \frac{2}{3} \\ \frac{21}{6} + \frac{4}{6} \\ \frac{25}{6}$
