c) |-1,(3)| =................;
d) |+5 • 1/2| =................;
e) |-4/+5| =...................;
f) |4/5 - 5/4| =....................;
Cine explica cel mai bine primeate coroana

Answer 1

a)|0,7|=0,7

$b) | - \frac{3}{5} | = \frac{3}{5}$

c)|-1,(3)|=1,3

$d) | + 5 \times \frac{1}{2} | = |5 \times \frac{1}{2} | = | \frac{5}{2} | = \frac{5}{2} \\ \\ e) | \frac{ - 4}{ + 5} | = | - \frac{4}{5} | = \frac{4}{5} \\ \\ f) | \frac{4}{5} - \frac{5}{4} | = | - \frac{9}{20} | = \frac{9}{20}$
