Question

1 3/5+1,8 *1/2 2) 6-4 8/15 :2,2;

Answer 1

$1) \\ \frac{8}{5} + \frac{9}{5} \times \frac{1}{2} = \frac{8}{5} + \frac{9}{10} = 2.5 \\ \\ 2) \\ 6 - \frac{68}{15} \div \frac{11}{5} = 6 - \frac{68}{15} \times \frac{5}{11} = 6 - \frac{68}{3} \times \frac{1}{11} = 6 - \frac{68}{33} = 3 \frac{31}{33}$
