Answer 1

$a) \frac{4}{2} = 2$

$\frac{8}{2} = 4$

$\frac{12}{2} = 6$

$\frac{16}{2} = 8$

$\frac{20}{2} = 10$

$b) \frac{4}{4} = 1$

$\frac{8}{4} = 2$

$\frac{12}{4} = 3$

$\frac{16}{4} = 4$

$\frac{20}{4} = 5$

$c) \frac{6}{2} = 3$

$\frac{10}{2} = 5$

$\frac{14}{2} = 7$

$\frac{18}{2} = 9$

$\frac{20}{2} = 10$

$d) \frac{8}{4} = 2$

$\frac{24}{4} = 6$

$\frac{28}{4} = 7$

$\frac{32}{4} = 8$

$\frac{40}{4} = 10$

$e) \frac{18}{3} = 6$

$\frac{21}{3} = 7$

$\frac{24}{3} = 8$

$\frac{27}{3} = 9$

$\frac{30}{3} = 10$
