Answer 1

Resposta:

5/9 -(-1/2+5/6) +(-2/3+1)

5/9 -(-3/6+5/6) +(-2/3+3/3)

5/9 -(2/6) +(1/3)

5/9-2/6+1/3

5/9 -1/3+1/3

= 5/9

Answer 2

Resposta: 7/18

5/9 - ( -1/2 + 5/6 ) + ( -2/3 + 1)

Explicação passo-a-passo:

( -1/2 + 5/6 ) mmc = 6

-3/6 + 5/6 = 2/6 = 1/3

( -2/3 + 1) mmc = 3

-2/3 + 3/3 = 1/3

agora podemos escrever

5/9 - 1/3 + 1/3 = 5/9
