Question

3 5/9 * 1 1/8 - 11 1/5 : 9 1/3
2 1/3α + 1 1/15α = 1 1/6

Answer 1

$3 frac{5}{9} * 1 frac{1}{8} - 11 frac{1}{5} : 9 frac{1}{3} = frac{32}{9} * frac{9}{8} - frac{56}{5} * frac{3}{28} =4- frac{6}{5} =2 frac{4}{5}$

$2 frac{1}{3} alpha + 1 frac{1}{15} alpha = 1 frac{1}{6} \\ 3 frac{5+1}{15} alpha = frac{7}{6} \\ alpha = frac{7}{6} : frac{17}{5} \\ alpha = frac{35}{102}$
