Пожалуйста помогите сделать

Answer 1

$\frac{1}{6} + \frac{1}{9} = \frac{3}{18} + \frac{2}{18} = \frac{5}{18}$
$\frac{2}{10} + \frac{6}{15} = \frac{6}{30} + \frac{12}{30} = \frac{18}{30} = \frac{9}{15} = \frac{3}{5} = 0.6$
$\frac{3}{4} + \frac{5}{18} = \frac{27}{36} + \frac{10}{36} = \frac{37}{36} = 1 \frac{1}{36}$
$\frac{4}{210} + \frac{5}{140} = \frac{8}{420} + \frac{15}{420} = \frac{23}{420}$
