Answer 1

1) 1/4:5/6= 1/4*6/5= 3/10
2) 4/9-3/10= 40/90-27/90= 13/90

Answer 2

$frac{4}{9} - frac{1}{4} div frac{5}{6} = frac{4}{9} - frac{1}{4} times frac{6}{5} = frac{4}{9} - frac{1}{2} times frac{3}{5} = frac{4}{9} - frac{3}{10} = frac{4 times 10 - 3 times 9}{9 times 10} = frac{40 - 27}{90} = frac{13}{90}$
