Question

49:1 3/4 -15,8+2 1/3
​

Answer 1

Объяснение:

$49 \div 1 \frac{3}{4} - 15.8 + 2 \frac{1}{3} = \\ \\ = 49 \div \frac{7}{4} - 15.8 + \frac{7}{3} = \\ \\ = \frac{49 \times 4}{7} - 15.8 + \frac{7}{3} = \\ \\ = 28 - 15.8 + \frac{7}{3} = \\ \\ = \frac{28}{1} - \frac{79}{5} + \frac{7}{3} = \\ \\ = \frac{420}{15} - \frac{237}{15} + \frac{35}{15} = \frac{218}{15 } = 14 \frac{8}{15}$
