Pls ajutor​

Answer 1

$0.5 + \frac{4}{33} \times ( - 0.25 + 13 \frac{1}{2} ) = \\ \\ = \frac{5}{10} + \frac{4}{33} \times ( - \frac{25}{100} + \frac{27}{2} ) = \\ \\ = \frac{1}{2} + \frac{4}{33} \times ( - \frac{25}{100} + \frac{1350}{100} ) = \\ \\ = \frac{1}{2} + \frac{4}{33} \times \frac{53}{4} = \\ \\ = \frac{1}{2} + \frac{53}{33} = \\ \\ = \frac{33 + 106}{66} = \\ \\ = \frac{139}{66}$
