Question

Вычислите: -0,38:-1,9-0,23*(-0,13)2,4*12:(-0,12)​

Answer 1

$- 0.38 \div ( - 1.9) - 0.23 \times ( - 0.13) \times 2.4 \times 12 \div ( - 0.12) = - \frac{19}{50} \div ( - \frac{19}{10} ) - \frac{23}{100} \times ( - \frac{13}{100} ) \times \frac{12}{5} \times 12 \div ( - \frac{3}{25} ) = \frac{19}{50} \times \frac{10}{19} - \frac{23}{25} \times \frac{13}{100} \times \frac{12}{5} \times 3 \times \frac{25}{3} = \frac{1}{5} - \frac{23}{25} \times \frac{13}{100} \times 4 \times 3 \times 5 = \frac{1}{5} - \frac{23}{5} \times \frac{13}{25} \times 3 = \frac{1}{5} - \frac{897}{125} = - \frac{872}{125} = - 6.976$
