Question

me ajuda por favorrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr

Answer 1

Resposta:

5/18

Explicação passo-a-passo:

Primeiro resolvemos os colchetes:

(-5/4) + (7/4)

Como os denominadores já são iguais:

-5 +7 = 2

Logo -> 2/4

Agora, resolvendo a soma:

(-2/9) + (2/4)

Fazendo o M.M.C (mínimo múltiplo comum) e dividindo denominador/ multiplicando pelo numerador:

-8/36 + 18/36 = 10/36

Simplificando...

5/18

Espero ter ajudado!!
