Va rog, repede
Dau coroana si multe puncte

Answer 1

3.

$- \frac{10}{3} = - 3.(3)$

Ordinea este:

$- 3, - 3.3, - \frac{10}{3}$

4.

$a = \frac{1}{2} \times \frac{4}{3} - \frac{1}{3} \times \frac{6}{5} - ( - \frac{2}{3} )$

$a = \frac{2}{3} - \frac{2}{5} + \frac{2}{3}$

$a = \frac{10}{15} - \frac{6}{15} + \frac{10}{15}$

$a = \frac{14}{15}$

$|a| = | \frac{14}{15} | = \frac{14}{15}$
