Answer 2

$1)0.7 + \frac{1}{5} = \frac{7}{10} + \frac{1}{5} = \frac{7 + 2}{10} = \frac{9}{10} = 0.9$

$2) \frac{3}{4} - 0.15 = \frac{3}{4} - \frac{3}{20} = \frac{15 - 3}{20} = \frac{12}{20} cokrashaem \: na \: 4 = \frac{3}{5} = 0.6$

$3) \frac{19}{50} + 0.02 = \frac{19}{50} + \frac{1}{50} = \frac{19 + 1}{50} = \frac{20}{50} cokrashaem \: na \: 10 = \frac{2}{5} = 0.4$
