Answer 1

Olá!

Para simplificar uma fração devemos dividir simultaneamente o numerador (parte superior) e denominador (parte inferior) por um número inteiro maior que 1.

Simplificando as frações...

A) $\large\rm{\dfrac{4}{8}=\dfrac{4\div 2}{8\div 2}=\dfrac{2\div 2}{4\div 2}=\boxed{\blue{\dfrac{1}{2}}}}$

B) $\large\rm{\dfrac{72}{144}=\dfrac{72 \div 6}{144 \div 6}=\dfrac{12 \div 6}{24 \div 6}= \dfrac{2 \div 2}{4 \div 2} = \boxed{\blue{\dfrac{1}{2}}}}$

C) $\large\rm{\dfrac{35}{80}= \dfrac{35 \div 5}{80 \div 5} = \boxed{\blue{\dfrac{7}{16}}}}$

D) $\large\rm{\dfrac{21}{35}= \dfrac{21 \div 7}{35 \div 7} =\boxed{\blue{\dfrac{3}{5}}}}$

E) $\large\rm{\dfrac{192}{200}= \dfrac{192 \div 4}{200 \div 4} = \dfrac{48 \div 2}{50 \div 2} =\boxed{\blue{\dfrac{24}{25}}}}$

F) $\large\rm{\dfrac{3}{15}= \dfrac{3 \div 3}{15 \div 3} =\boxed{\blue{\dfrac{1}{5}}}}$

G) $\large\rm{\dfrac{45}{63}= \dfrac{45 \div 9}{63 \div 9} =\boxed{\blue{\dfrac{5}{7}}}}$

H)$\large\rm{\dfrac{8}{12}= \dfrac{8 \div 4}{12 \div 4} =\boxed{\blue{\dfrac{2}{3}}}}$

I) $\large\rm{\dfrac{3 \div 3}{6 \div 3}=\boxed{\blue{\dfrac{1}{2}}}}$

J) $\large\rm{\dfrac{54}{90}= \dfrac{54 \div 6}{ 90\div 6}=\dfrac{9 \div3 }{15 \div 3} =\boxed{\blue{\dfrac{3}{5}}}}$
