1) 11 \frac{5}{8} + 7  \frac{1}{6} =  \frac{93^{(3} }{8} +  \frac{43 ^{(4} }{6} =  \frac{279}{24} +  \frac{172}{24} =  \frac{279 + 172}{24} =  \frac{351}{24} =  \frac{119}{4} = 29  \frac{3}{4}
2) 29 \frac{3}{4} : 3 \frac{5}{12} =  \frac{119}{4} : \frac{41}{12} =  \frac{119}{4} *  \frac{12}{41}  =  \frac{119 * 12}{4 * 41} =  \frac{119 * 3}{41} =  \frac{357}{41} = 8  \frac{29}{41}
