por favor gente me ajudem :(

Answer 1

Resposta:

67/15.

Explicação passo a passo:

{[(1/2 - 5/10) - (1/3 + 1/4) + 1/2 ÷ 3/4 + 1/5] + 3} =

{[(1/2 - 5/10) - (1/3 + 1/4) + 1/2 x 4/3 + 1/5] + 3} =

{[(1/2 - 5/10) - (1/3 + 1/4) + 4/6 + 1/5] + 3} =

Igualando os denominadores:

{[(5/10 - 5/10) - (4/12 + 3/12) + 20/30 + 6/30] + 3} =

{[7/12 + 26/30] + 3} =

Igualando os denominadores:

{[35/60 + 53/60] + 3 =

88/60 + 3 =

Igualando os denominadores:

88/60 + 180/60 =

268/60 = 67/ 15.
