Question

Alguém sabe fazer essa expressao?

Answer 1

Resposta:

$\frac{1}{2} +[2*(1-\frac{1}{2} ]  = \frac{1}{2} +[2*(\frac{2}{2} -\frac{1}{2} ] =\frac{1}{2} +[2*\frac{(2-1)}{2}  ] =\frac{1}{2} +[2*\frac{1}{2} ] =\frac{1}{2} +1\\\\\frac{1}{2} +[2*(1-\frac{1}{2} ] = \frac{1}{2} +\frac{2}{2} =\frac{(1+2)}{2}$

$\frac{1}{2} +[2*(1-\frac{1}{2} ]=\frac{3}{2}$

Answer 2

Resposta:

3/2

Explicação passo-a-passo:

1/2 + [2 × (1 - 1/2)]

1/2 + [2 × 1/2]

1/2 + [2/2]

1/2 + 1 ⇒mmc = 2

1 + 2/2

3/2
