Multiplicación y división de fracciones

Resolvamos:

2)

$2\frac{8}{2} \times \frac{1}{2}=\frac{12}{2}\times \frac{1}{2}=\frac{12 \times 1}{2 \times 2}=\frac{12}{4} =3$

3)

$\frac{3}{10} \times 4\frac{5}{6}=\frac{3}{10}\times \frac{29}{6}=\frac{3 \times 29}{10 \times 6}=\frac{87}{60} =\frac{29}{20}$

4)

$\frac{1}{8} \times 8\frac{1}{3}=\frac{1}{8}\times \frac{25}{3}=\frac{1 \times 25}{8 \times 3}=\frac{25}{24}$

6)

$4\frac{1}{2} \div \frac{1}{4} = \frac{9}{2}\div \frac{1}{4} = \frac{9}{2}\times \frac{4}{1} = \frac{9 \times 4}{2 \times 1} = \frac{36}{2} = 18$

7)

$5\frac{1}{3} \div \frac{1}{2} = \frac{16}{3}\div \frac{1}{2} = \frac{16}{3}\times \frac{2}{1} = \frac{16 \times 2}{3 \times 1} = \frac{32}{3}$

8)

$\frac{3}{10}\div \frac{5}{6} = \frac{3}{10}\times \frac{6}{5} = \frac{3 \times 6}{10 \times 5} = \frac{18}{50} = \frac{9}{25}$
