Question

reduza as frações ao mesmo denominador: a) 5/3 ; 2/4 b) 6/5 ; 3/2 ; 4/10

Answer 1

Resposta:

a) 10/6; 3/6

b) 12/10; 15/10;4/10

Explicação passo-a-passo:

a) 5/3 ; 2/4

2/4=2÷2/4÷2=1/2

5/3; 1/2

mmc(3,2)

3,2|2

3,1|3

1,1|1

mmc(3,2)=2.3=6

5/3 =[(6÷3)×5]/6=[2×5]/62=10/6

1/2 =>[(6÷2)×1]/6=[3×1]/6=3/6

b)

6/5 ; 3/2 ; 4/10

4/10=4÷2/10÷2=2/5

6/5 ; 3/2 ; 2/5

mmc(2,5)

2,5|2

1,5|5

1,1|1

mmc(2,5)=2.5=10

6/5=[(10÷5)×6]/10=[2×6]/10=12/10

3/2=[(10÷2)×3]/10=[5×3]/10=15/10

2/5=[(10÷5)×2]/10=[2×2]/10=4/10
