Answer 1

Răspuns:

a) $\frac{9}{10} :6$= $\frac{3x3}{5x2}$ $* \frac{1}{2x3}$= $\frac{3}{20}$

b) $\frac{6}{7} :3$ = $\frac{6}{7} *\frac{1}{3}$= $\frac{2}{7}$

e) $\frac{6x4+1}{15} :15$= $\frac{25}{15} *\frac{1}{15}$= $\frac{5x5}{5x3}$ *$\frac{1}{3x5}$= $\frac{1}{9}$

f) $\frac{8}{9}$ : 5= $\frac{8}{9} *\frac{1}{5}$= $\frac{8}{45}$
