Answer 1

$15) \frac{12}{n + 2}$

$a) \frac{12}{2 + 2} = \frac{12}{4} = 3$

$\frac{12}{6 + 2} = \frac{12}{8} = \frac{3}{2}$

$b) \frac{12}{3 + 2} = \frac{12}{5}$

$\frac{12}{9 + 2} = \frac{12}{11}$

$c) \frac{12}{11 + 2} = \frac{12}{13}$

$\frac{12}{65 + 2} = \frac{12}{67}$

$d) \frac{12}{3 + 2} = \frac{12}{5} = 2.4$

$\frac{12}{6 + 2} = \frac{12}{8} = 1.5$

$e) \frac{12}{25 + 2} = \frac{12}{27} = 0.(4)$

$\frac{12}{52 + 2} = \frac{12}{54} = 0.(2)$

$f) \frac{12}{178 + 2} = \frac{12}{180} = 0.0(6)$

$\frac{12}{358 + 2} = \frac{12}{360} = 0.0(3)$
