Answer 1

Resposta:

$\\ a) \frac{300}{700} \frac{:2}{:2} = \frac{150}{350} \frac{:2}{:2} = \frac{75}{175} \frac{:5}{:5} = \frac{15}{35} \frac{:5}{:5} =\frac{3}{7}$

Tbm eliminam-se os zeros ficando 3/7

$\\ b) \frac{125}{625} \frac{:5}{:5} = \frac{25}{125} \frac{:5}{:5} = \frac{5}{25} \frac{:5}{:5} = \frac{1}{5}$

Tbm podes dividir 125: 125 = 1

                              625: 125 = 5         vc obtém 1/5  

$\\ c) \frac{64}{256} \frac{:2}{:2} = \frac{32}{128} \frac{:2}{:2} = \frac{16}{64} \frac{:2}{:2} = \frac{8}{32} \frac{:2}{:2}= \frac{4}{16} \frac{:4}{:4} = \frac{1}{4}$

64 : 64 = 1

256 : 64 = 4        vc obtém 1/4

$\\ d) \frac{250}{1500} \frac{:5}{:5} = \frac{50}{300} \frac{:5}{:5} =\frac{10}{60} \frac{:10}{: 10} = \frac{1}{6}$

250 : 250 = 1

1500 : 250 = 6
