Answer 1

Ответ:

$\frac{5 {}^{3} }{5 {}^{2} } = \frac{125}{25} = 5 \\ \frac{6 \times 8 \times 12}{10 \times 8 \times 40} = \frac{576}{3200} = 0.18 \\ ( \frac{9}{50} ) \\ \frac{2 + \frac{1}{3} + \frac{1}{2} }{2 - \frac{1}{3} - \frac{1}{2} } = \frac{ \frac{17}{6} }{ \frac{7}{6} } = \frac{17}{7} \\ \frac{7}{5 - 0.1} \div \frac{5 - 0.1}{7} = \frac{7}{4.9} \div \frac{4.9}{7} = \frac{ \frac{7}{49} }{10} \times \frac{10}{7} = \frac{10}{49} \times 10 = \frac{100}{49} \\ \frac{3}{5} \times \frac{ {5}^{3} }{18} \times \frac{3}{5} = \frac{5 {}^{2} }{6} \times \frac{3}{5} = \frac{5}{2} = 2.5$
