Question

СРОЧНО Вычислите:
1/16-3/4
-2/3-(-1/2)
-5/18-(-1/24)

Answer 1

1.

$\frac{1}{16} - \frac{3}{4} = \frac{1}{16} - \frac{12}{16} = - \frac{11}{16}$

2.

$- \frac{2}{3} - ( - \frac{1}{2} ) = - \frac{2}{3} + \frac{1}{2} = - \frac{4}{6} + \frac{3}{6} = \\ - \frac{1}{6}$

3.

$- \frac{ 5}{18} - ( - \frac{1}{24} ) = - \frac{5}{18} + \frac{1}{24} = \\ - \frac{20}{72} + \frac{3}{72} = - \frac{17}{72}$

Answer 2

Ответ:

$\frac{1}{16 } - \frac{3}{4} = \frac{1 - 12}{16} = - \frac{11}{16}$

$- \frac{2}{3} - ( - \frac{1}{2}) = - \frac{2}{3} + \frac{1}{2} = - \frac{4 + 3}{6} = - \frac{1}{6}$

$- \frac{5}{18} - ( - \frac{1}{24}) = - \frac{5}{18} + \frac{1}{24} = - \frac{20 + 3}{72} = - \frac{17}{72}$
