$1)5 frac{5}{18} - 4 frac{7}{12} = 5 frac{10}{36} - 4 frac{21}{36} = \ 4 frac{46}{36} - 4 frac{21}{36} = frac{25}{36}$

$2) frac{25}{36} times frac{27}{25} = frac{3}{4}$

$3)1 frac{1}{4} + 1 frac{3}{8} = 1 frac{2}{8} + 1 frac{3}{8} = 2 frac{5}{8}$

$4) frac{3}{4} div 2 frac{5}{8} = frac{3}{4} times frac{8}{21} = frac{2}{7}$

Ответ:

$frac{2}{7}$
