Answer 1

Ответ:

4.

$3.5 + 3.5 - \frac{1}{3} \times 3.5 = 7 - \frac{3.5}{3} = \frac{21 - 3.5}{3} = \frac{17.5}{3} = \frac{35}{6} = 5 \frac{5}{6}$

5.

$1 - ( \frac{1}{4} + \frac{1}{9}) = 1 - \frac{9 + 4}{36} = 1 - \frac{13}{36} = \frac{23}{36}$

6.

$\frac{ 7\frac{1}{4} - 3 \frac{3}{4} }{2} = \frac{ \frac{29 - 15}{4} }{2} = \frac{ \frac{14}{4} }{2} = \frac{14}{8} = 1.75$
