Răspuns:
[tex]\boxed{\frac{3}{14}}[/tex]
Explicație pas cu pas:
[tex]\displaystyle{ \frac{15}{21} : \frac{10}{3} = \frac{15}{21} \cdot \frac{3}{10} }[/tex]
[tex]\displaystyle{ =\frac{15 \cdot 3}{21 \cdot 10} }[/tex]
[tex]\displaystyle{ = \frac{45}{210} ^{(15}}[/tex]
[tex]\displaystyle{ = \frac{3}{14} }[/tex]
Formula generala pentru impartirea fractiilor este:
[tex]\boxed{\frac{a}{b} : \frac{c}{d} = \frac{a}{b} \cdot \frac{d}{c}}[/tex]
