Question

Qualcule a simplificacao o resulto quando for possivel
A) 3/14+1/7=
B)2/5 + 1/10
C)2/4 + 2/5

Answer 1

Explicação passo-a-passo:

A)

3/14+1/7=(21+14)/98=35/98

3/14+1/7=(35÷7)/(98÷7)

3/4+1/7= 5/14

B)

2/5 + 1/10=(20+5)/50=25/50

2/5+1/10=(25÷25)/(50÷25)

2/5+1/10= 1/2

C)

2/4 + 2/5=(8+10)/20=18/20

2/4+2/5=(18÷2)/(20÷2)

2/4+2/5= 9/10

Answer 2

Vamos lá...

Resolução:

a)

3/14 + 1/7 ⇒mmc de 14, 17 = 14

3 + 2/14

5/14

b)

2/5 + 1/10 ⇒mmc de 5, 10 = 10

4 + 1/10

5/10 ÷ 5

1/2

c)

2/4 + 2/5

1/2 + 2/5⇒mmc de 2, 5 = 10

5 + 4/10

9/10

Bons estudos.
