Answer 1

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

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

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

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

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

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

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

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

3.

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

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

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

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

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