Answer:

Saludos R/  S = {-11/9}

Si definimos el número como "x", su cuarta parte es "1/4 x" luego

1/4 x + 5/9 = 1/4    restamos 5/9 a ambos lados

1/4 x = 1/4 - 5/9

1/4 x = 9/36 - 20/36

1/4 x = -11/36    y dividimos por 1/4 a ambos lados

    x = -11/36 / 1/4

    x = (-11*4) / (36*1)

    x = -44/36

   x = -11/9

Prueba

1/4(-11/9) + 5/9 =

-11/36 + 5/9 =

-11/36 + 20/36 =

       9/36 =

       1/4
