Answer 1

(1)

$\frac{1}{2} + \frac{2}{4} = \frac{2 + 2}{4} = \frac{4}{4} = 1$

(2)

$\frac{4}{4} + \frac{3}{2} = \frac{4 + 6}{4} = \frac{10}{4} = \frac{5}{2}$

(3)

$\frac{6}{3} - \frac{8}{4} = \frac{24 - 24}{12} = \frac{0}{12} = 0$

(4)

$\frac{3}{6} - \frac{4}{8} = \frac{12 - 12}{24} = \frac{0}{24} = 0$

(E) 1 )

$\frac{2}{6} \div \frac{5}{30} = \frac{2}{6} \times \frac{30}{5} = \frac{60}{30} = 2$

(2)

$\frac{8}{9} \div \frac{7}{6} = \frac{8}{9} \times \frac{6}{7} = \frac{48}{63} = \frac{16}{21}$

(3)

$\frac{8}{5} \div \frac{6}{10} = \frac{8}{5} \times \frac{10}{6} = \frac{80}{30} = \frac{40}{15} = \frac{8}{3}$

(4)

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