$15)a)0.(6) = \frac{6}{9} = \frac{2}{3}$

$b)2.(36) = \frac{236 - 2}{99} = \frac{234}{99} = \frac{78}{33} = \frac{26}{11}$

$c)5.(135) = \frac{5135 - 5}{999} = \frac{5130}{999} = \frac{1710}{333} = \frac{570}{111} = \frac{190}{37}$

$16)a)1.1(6) = \frac{116 - 11}{90} = \frac{105}{90} = \frac{35}{30} = \frac{7}{6}$

$b)2.708(3) = \frac{27083 - 2708}{9000} = \frac{24375}{9000} = \frac{4875}{1800} = \frac{975}{360} = \frac{195}{72} = \frac{65}{24}$

$c)1.25(78) = \frac{12578 - 125}{9900} = \frac{12453}{9900} = \frac{4151}{3300}$
