Решите задачу:

$1) \frac{1}{5}= \frac{1*2}{5*2} = \frac{2}{10}=0,2 \\ \\ 2)\frac{5}{8}= \frac{5*125}{8*125}= \frac{625}{1000}=0,625 \\ \\ 3)1 \frac{4}{5}= \frac{9}{5}= \frac{9*2}{5*2}= \frac{18}{10}=1,8 \\ \\ 4) \frac{1}{20}= \frac{1*5}{20*5}= \frac{5}{100}=0,05 \\ \\ 5) \frac{1}{25}= \frac{1*4}{25*4}= \frac{4}{100}=0,04$

$6) \frac{168}{40} = \frac{168 :4}{40:4}= \frac{42}{10}=4,2 \\ \\ 7) \frac{296}{80}= \frac{296:8}{80:8} = \frac{37}{10}=3,7 \\ \\ 8) \frac{6}{125}= \frac{6*8}{125*8} = \frac{48}{1000}=0,048 \\ \\ 9) \frac{26}{200}= \frac{26*5}{200*5}= \frac{130}{1000}=0,13$

$10) \frac{46}{250}= \frac{46*4}{250*4}= \frac{184}{1000}=0,184 \\ \\ 11) \frac{177}{300}= \frac{177:3}{300:3}= \frac{59}{100}=0,59 \\ \\ 12) \frac{66}{600}= \frac{66:6}{600:6}= \frac{11}{100}=0,11$
