Question

Reduza ao menor denominador comum as frações
A) 7/2, 2/3, 4/5, 5/7
B) 1,1/8, 9/10, 3/20

Answer 1

Resposta:

Explicação passo a passo:

a

mmc (2,3,5,7)=210

7/2=735/210

2/3=140/210

4/5=168/210

5/7=150/210

b

8,10,20|2

4,5,10|2

2,5,5|2

1,5,5|5

1,1,1

mmc(8,10,20)=2.2.2.5=40

1=40/40

1/8=5/40

9/10=36/40

3/20=6/40
