Answer 1

Explicação passo-a-passo:

a) $\sf \dfrac{72}{144}=\dfrac{72\div72}{144\div72}=\red{\dfrac{1}{2}}$

b) $\sf \dfrac{35}{80}=\dfrac{35\div5}{80\div5}=\red{\dfrac{7}{16}}$

c) $\sf \dfrac{21}{35}=\dfrac{21\div7}{35\div7}=\red{\dfrac{3}{5}}$

d) $\sf \dfrac{192}{200}=\dfrac{192\div8}{200\div8}=\red{\dfrac{24}{25}}$

e) $\sf \dfrac{3}{15}=\dfrac{3\div3}{15\div3}=\red{\dfrac{1}{5}}$

f) $\sf \dfrac{45}{63}=\dfrac{45\div9}{63\div9}=\red{\dfrac{5}{7}}$

g) $\sf \dfrac{8}{12}=\dfrac{8\div4}{12\div4}=\red{\dfrac{2}{3}}$

h) $\sf \dfrac{3}{6}=\dfrac{3\div3}{6\div3}=\red{\dfrac{1}{2}}$

i) $\sf \dfrac{54}{90}=\dfrac{54\div18}{90\div18}=\red{\dfrac{3}{5}}$

Answer 2

Resposta:

a) $\frac{72}{144}$ =

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

b) $\frac{35}{80}$

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

c) $\frac{21}{35}$

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

d) $\frac{192}{200}$

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

e) $\frac{3}{15}$

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

f) $\frac{45}{63}$

$\frac{45}{63} = \frac{15}{21} = \frac{5}{7}$

g) $\frac{8}{12}$

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

h) $\frac{3}{6}$

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

i) $\frac{54}{90}$

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

espero que isso ajude vc
