Question

4 5/9-2 1/9=(4-2)+(5/9-1/9)=2 4/9

Answer 1

(9*4+5)-(9*2+1)=(36+5)-(18+1)= 41/9-19/9..........

Answer 2

$4 \frac{5}{9} - 2 \frac{1}{9} = 4 \frac{5}{9} = \frac{4 \times 9 + 5}{9} = \frac{41}{9} = 2 \frac{1}{9} = \frac{2 \times 9 + 1}{9} = \frac{19}{9} = \frac{41}{9} - \frac{19}{9} = \frac{41 - 9}{9} = \frac{22}{9} = 2 \frac{4}{9}$
