Question

2(5-5/18-47)×1 2/25÷(1 1/4+1 3/8)

Answer 1

$- 35 \frac{171}{175}$

Пошаговое объяснение:

$2(5 - \frac{5}{18} - 47) \times 1 \frac{2}{25} \div (1 \frac{1}{4} + 1 \frac{3}{8} ) = - 35 \frac{171}{175}$

1)

$5 - \frac{5}{18} = 4 \frac{13}{18}$

2)

$4 \frac{13}{18} - 47 = - 43 \frac{13}{18}$

3)

$1 \frac{1}{4} + 1 \frac{3}{8} = 2 \frac{5}{8}$

4)

$2 \times ( - 43 \frac{13}{18} ) = - 87 \frac{4}{9}$

5)

$- 87 \frac{4}{9} \times 1 \frac{2}{25} = - 94 \frac{11}{25}$

6)

$- 94 \frac{11}{25} \div 2 \frac{5}{8} = - 35 \frac{171}{175}$
