Question

Помогите решить номер 319 и 321

Answer 1

319.

|-200|+|-76|+|23|=200+76+23=299

|-343|-|299|+|-88|=343-299+88=132

|901|+|-252|-|-348|=901+252-348=805

|116|+|-304|+|-64|=116+304+64=484

321.

|345|÷|-69|=345÷69=5

|-0,101|×|33|=0,101×33=3,333

6)

$| - \frac{35}{93} | \div | - 3.72| = \frac{35}{39} \div 3.72 = \frac{35}{39} \times \frac{25}{93} = \frac{875}{3627}$

3)

$| - \frac{ 40}{81} | \times | - \frac{27}{55} | = \frac{40}{81} \times \frac{27}{55} = \frac{8}{3} \times \frac{1}{11} = \frac{8}{33}$

4)

$| \frac{125}{169} | \div | - \frac{25}{26} | = \frac{125}{169} \times \frac{26}{25} = \frac{5}{13} \times 2 = \frac{10}{13}$

5)

$| - 3.8| \times | - \frac{5}{57} | = 3.8 \times \frac{5}{57} = \frac{19}{5} \times \frac{5}{57} = \frac{1}{3}$
