3/4÷2/5=3/4×5/2=15/8

4/6÷5/11=4/6×11/5=20/30 simplificam 0-urile si rămânem cu 2/3

7/25÷23/25=7/25×25/23 simplificam 25 cu 25 și rămânem cu 7/23

3/7÷8/17=3/7×17/8=41/56

[tex] \frac{3}{4} \div \frac{2}{5} = \frac{3}{4} \times \frac{5}{2} = \frac{15}{8} \\ \\ \\ \frac{4}{6} \div \frac{5}{11} = \frac{4}{6} \times \frac{11}{5} = \frac{44}{30} \\ \\ \frac{7}{25} \div \frac{23}{25} = \frac{7}{25} \times \frac{25}{23} = \frac{175}{575} \\ \\ \\ \frac{3}{17} \div \frac{8}{17} = \frac{3}{17} \times \frac{17}{8} = \frac{51}{136} [/tex]
