Answer 1

$1) \frac{1}{2}=\frac{1*5}{2*5} =\frac{5}{10} = 0,5\\ \\ 2) \frac{1}{4}=\frac{1*25}{4*25} =\frac{25}{100} = 0,25\\ \\ 3) \frac{3}{8}=\frac{3*125}{8*125} =\frac{375}{1000} = 0,375\\ \\4) \frac{11}{20}=\frac{11*5}{20*5} =\frac{55}{100} = 0,55\\ \\5) \frac{14}{25}=\frac{14*4}{25*4} =\frac{56}{100} = 0,56\\ \\6) \frac{57}{40}=\frac{57*25}{40*25} =\frac{1425}{1000} = 1,425.$
