Answer 1

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

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

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

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

Ответ:

$\frac{2}{7}$
