Answer 1

$6 \times 2 \frac{1}{2} \times ( \frac{27}{20} - \frac{3}{4} ) - 4 \frac{8}{9} \times \frac{9}{11} = 6 \times \frac{5}{2} \times \frac{3}{5} - \frac{44}{9} \times \frac{9}{11} = 9 - 4 = 5$

Answer 2

1)27/20 - 3/4 = 27/20 - 15/20 = 12/20 =  3/5
2) 6 * 5/2 = 30/2 = 15
3)3/5 * 15 = 9
4)44/9 * 9/11 =44/11=4
5) 9 - 4 = 5
