Answer 1

$1. \\ frac{1}{2} = frac{1cdot 5}{2cdot 5} = frac{5}{10} = 0,5 \\ frac{3}{8} = frac{3cdot 125}{8cdot 125} = frac{375}{1000} = 0,375 \\ 2 frac{7}{100} = 2,07$

$3 frac{11}{20} = 3 frac{11cdot 5}{20cdot 5} = 3 frac{55}{100} = 3,55 \\ frac{23}{40} = frac{23cdot 25}{40cdot 25} = frac{575}{1000} = 0,575$

$frac{49}{125} = frac{49cdot 8}{125cdot 8} = frac{392}{1000} = 0,392 \\ 6 frac{4}{5} = 6 frac{4cdot 2}{5cdot 2} = 6 frac{8}{10} = 6,8 \\ 1 frac{47}{10000} = 1,0047$

$2. \\ frac{1}{5} = frac{1cdot 2}{5cdot 2} = frac{2}{10} = 0,2 \\ frac{3}{4} = frac{3cdot 5}{4cdot 5} = frac{15}{20} = frac{15cdot 5}{20cdot 5} = frac{75}{100} = 0,75$

$5 frac{23}{1000} = 5,023$

$frac{17}{20} = frac{17cdot 5}{20cdot 5} = frac{85}{100} = 0,85$

7 11/40 = 7 11*25/40*25 = 7 275/1000 = 7,275

$frac{3}{125} = frac{3cdot 8}{125cdot 8} = frac{24}{1000} = 0,024 \\ 3 frac{9}{25} = 3 frac{9cdot 4}{25cdot 4} = frac{36}{100} = 0,36 \\ 1 frac{7}{10} = 1,7$

3.

3/5 = 3*2/5*2 = 6/10 = 0,6

$frac{1}{8} = frac{1cdot 125}{8cdot 125} = {125}{1000} = 0,125 \\ 4 frac{23}{1000} = 4,023$

$2 frac{7}{20} = 2 frac{7cdot 5}{20cdot 5} = 2 frac{35}{100} = 2,35 \\ frac{17}{40} = frac{17cdot 25}{40cdot 25} = frac{425}{1000} = 0,425 \\ frac{31}{125} = frac{31cdot 8}{125cdot 8} = frac{248}{1000} = 0,248$

$7 frac{6}{25} = 7 frac{6cdot 4}{25cdot 4} = 7 frac{24}{100} = 7,24 \\ frac{19}{1000} = 0,019$

$4. \\ frac{4}{5} = frac{4cdot 2}{5cdot 2} = frac{8}{10} = 0,8 \\ frac{3}{40} = frac{3cdot 25}{40cdot 25} = frac{75}{1000} = 0,075 \\ frac{9}{1000} = 0,009 \\ 8 frac{11}{20} = 8 frac{11cdot 5}{20cdot 5} = 8 frac{55}{100} = 8,55 \\ 6 frac{33}{80} = 6 frac{33cdot 125}{80cdot 125} = 6 frac{4125}{10000} = 6,4125 \\ 2 frac{7}{125} = 2 frac{7cdot 8}{125cdot 8} = 2 frac{56}{1000} = 2,056 \\ frac{4}{25} = frac{4cdot 4}{25cdot 4} = frac{16}{100} = 0,16 \\ 1 frac{7}{200} = 1 frac{7cdot 5}{200cdot 5} = 1 frac{35}{1000} = 1,035$
