Answer 1

Ответ:

$1)1 \frac{5}{9} \div \frac{7}{2} = \frac{14}{9} \times \frac{2}{7} = \frac{4}{9}$

$2)7 - \frac{4}{9} = 6 \frac{9}{9} - \frac{4}{9} =6 \frac{5}{9}$

$3)6 \frac{5}{9} \div \frac{20}{27} = \frac{59}{9} \times \frac{27}{20} = \frac{59 \times 3}{20} = \frac{177}{20} = 8 \frac{17}{20}$
