Question

Calculati: 0,0(6)+ 15supra64 × 1,28-2×[0,125-0,08(3)] ... Va rog frumos sa ma ajutați

Answer 1

$0.0(6) + \frac{15}{64} \times 1.28 - 2 \times [0,125 - 0,08(3)] = \\ \\ \frac{1}{15} + \frac{15}{64} \times \frac{128}{100} - 0,25 + \frac{1}{6} = \\ \\ \frac{1}{15} + \frac{15}{1} \times \frac{1}{50} - 0.25 + \frac{1}{6} = \\ \\ \frac{1}{15} + \frac{3}{10} - \frac{1}{4} + \frac{1}{6} = \\ \\ \frac{(4 + 18 - 15 + 10)}{60} = \frac{17}{60}$
