Answer 1

i.13/4×23/6= 379/24

ii.13/4+23/6= 39+46 /12= 85/12

iii.13/4×6/17=39/34.......

Answer 2

$2 \frac{5}{4} \times 3 \frac{5}{6} = ( \frac{2}{1} + \frac{5}{4}) \times ( \frac{3}{1} + \frac{5}{6} ) \\ \: \: \: \: \: \: = \frac{13}{4} \times \frac{23}{6} \\ = \frac{299}{24}$

$(2) \: \\ 2 \frac{5}{4 } + 3 \frac{5}{6} = \frac{2}{1} + \frac{5}{4} + \frac{3}{1} + \frac{5}{6} \\ = 5 + \frac{50}{24} = 5 + \frac{25}{12} = \frac{60 + 25}{12} = \frac{85}{12}$

$2 \frac{5}{4} \div 2 \frac{5}{6} = (2 + \frac{5}{4} ) \div (2 + \frac{5}{6} ) \\ = \frac{13}{2} \div \frac{17}{6} \\ = \frac{13}{2} \times \frac{6}{17} = \frac{39}{17}$
