614. Напишите числа в виде неправильной дроби: 1) 3 1/4 ; 5 2/3 ; 7 5/8 ; 11 3/4 ; 29 3/6 ; 17 5/9 ; 8 5/6 .

1) $$3\frac{1}{4} = \frac{3 \cdot 4 + 1}{4} = \frac{12+1}{4} = \frac{13}{4}$$

$$5\frac{2}{3} = \frac{5 \cdot 3 + 2}{3} = \frac{15+2}{3} = \frac{17}{3}$$

$$7\frac{5}{8} = \frac{7 \cdot 8 + 5}{8} = \frac{56+5}{8} = \frac{61}{8}$$

$$11\frac{3}{4} = \frac{11 \cdot 4 + 3}{4} = \frac{44+3}{4} = \frac{47}{4}$$

$$29\frac{3}{6} = \frac{29 \cdot 6 + 3}{6} = \frac{174+3}{6} = \frac{177}{6}$$

$$17\frac{5}{9} = \frac{17 \cdot 9 + 5}{9} = \frac{153+5}{9} = \frac{158}{9}$$

$$8\frac{5}{6} = \frac{8 \cdot 6 + 5}{6} = \frac{48+5}{6} = \frac{53}{6}$$

Ответ: $$\frac{13}{4}; \frac{17}{3}; \frac{61}{8}; \frac{47}{4}; \frac{177}{6}; \frac{158}{9}; \frac{53}{6}$$
