55 : 11/12
18/19 : 6

Answer 1

4/5 : 3/13=4/5*13/3=52/15=3 7/15
4/9 : 16/45=4/9*45/16=5/4=1 1/4
55 : 11/12=55*12/11=60
18/19 : 6 =18/19*1/6=3/19

Answer 2

$frac{4}{5} : frac{3}{13} = frac{4*13}{5*3} = frac{52}{15} =3 frac{7}{15}$
$frac{4}{9} : frac{16}{45} = frac{4*45}{9*16} = frac{1*5}{1*4} = 1frac{1}{4}$
$55: frac{11}{12} = frac{55*12}{1*11} = frac{5*12}{1} =60$
$frac{18}{19} :6= frac{18*1}{19*6} = frac{3}{19}$
