Question

(5-11 7/8*2,5):0,0625​

Answer 1

$(5 - 11 frac{7}{8} times 2.5) div 0.0625=-389$

1)

$11 frac{7}{8} times 2 frac{5}{10} = frac{95}{8} times frac{25}{10} = \ = frac{95 times 25}{8 times 10} = frac{95 times 5}{8 times 2} = frac{475}{16} = \ = 29 frac{11}{16}$

2)

$5 - 29 frac{11}{16} = 4 frac{16}{16} - 29 frac{11}{16} = - 24 frac{5}{16}$

3)

$- 24 frac{5}{16} div frac{625}{10000} = - frac{389}{16} times frac{10000}{625} =$

= -389 ×16/16 = -389.
