Question

scrie fiecare dintre fractiile

Answer 1

$\frac{15}{3} = \frac{3+3+9}{3} = \frac{3}{3} + \frac{3}{3} + \frac{9}{3}$
$\frac{15}{3} = \frac{7+2+6}{3} = \frac{7}{3} + \frac{2}{3} + \frac{6}{3}$

$\frac{19}{7} = \frac{7+7+5}{7} = \frac{7}{7} + \frac{7}{7} + \frac{5}{7}$$\frac{19}{7} = \frac{8+9+2}{7} = \frac{8}{7} + \frac{9}{7} + \frac{2}{7} [tex]\frac{25}{10} = \frac{10+10+5}{10} = \frac{10}{10} + \frac{10}{10} + \frac{5}{10}$$\frac{25}{10} = \frac{11+13+1}{10} = \frac{11}{10} + \frac{13}{10} + \frac{1}{10}$

Fractie echiunitara : numaratorul = numitorul
Fractie subunitara : numaratorul < numitorul
Fractie supraunitara : numaratorul > numitorul

numarator = ce este scris peste linia fractie
numitorul = ce e scris sub linia fractiei
