Question

выполните действия (3,8 • 1,75 : 0,95 - 1,02) : 2,3 + 0,4

Answer 1

$( \frac{38}{10} \times \frac{175}{100} \div \frac{95}{100} - \frac{102}{100} ) \div \frac{23}{10} + \frac{4}{10} = ( \frac{38 \times 175 \times 100}{10 \times 100 \times 95} - \frac{102}{100} ) \times \frac{10}{23} + \frac{4}{10} = (7 - 1.02) \times \frac{10}{23} + \frac{4}{10} = \frac{598 \times 10}{100 \times 23} + \frac{4}{10} = \frac{26}{10} + \frac{4}{10} = \frac{30}{10} = 3$
