Question

Care este rotunjirea la unitati a rezultatului calcului 2/3 + 5/6 : 1/3

Answer 1

2/3+5/6:1/3=
=2/3+5/6 *3/1=
=2/3+5/2 =
=(4+15)/6=
=19/6=3,1(6)
rotunjirea  = 3

Answer 2

$\frac{2}{3}+ \frac{5}{6} : \frac{1}{3} \to \frac{2}{3} + \frac{5}{6} * \frac{3}{1} \\ \\ \to \frac{2}{3} + \frac{5*3}{6*1} \to \frac{2}{3} + \frac{15}{6}(simplific.cu.3)\to \frac{2}{3} + \frac{5}{2} \\ \\ \to \frac{(15+4)}{6}\to \frac{19}{6}=3,1(6)\to rotunjirea \to\boxed{3}$
