Answer 1

Resposta:

a)

$\frac{72}{144} = \frac{36}{72} = \frac{18}{36} = \frac{9}{18} = \frac{3}{6} = \frac{1}{2}$

b)

$\frac{35}{80} = \frac{7}{16}$

c)

$\frac{21}{35} = \frac{3}{5}$

d)

$\frac{192}{200} = \frac{96}{100} = \frac{48}{50} = \frac{24}{25}$

e)

$\frac{3}{15} = \frac{1}{5}$

f)

$\frac{45}{63} = \frac{15}{21}$

g)

$\frac{8}{12} = \frac{4}{6} = \frac{2}{3}$

h)

$\frac{3}{6} = \frac{1}{2}$

i)

$\frac{54}{90} = \frac{27}{45} = \frac{9}{15} = \frac{3}{5}$
