Respuesta:
a) 6/7
b) 51/20
c) 1/2
d) 31/24
Explicación paso a paso:
a) 1/7 + 3/7 + 2/7 = (1 + 3 +2 )/7 = 6/7
b) 3 1/2 + 1/5 + -3/4 = 70/20 + 4/20 - 15/20 = ( 70 + 4 - 15 ) / 20 = 51/20
c) -1/4 + 3/4 = ( -1 + 3 ) / 4 = 2/4 = 1/2
d) 2/3 + ( -1/8 + 3/4 ) = 16/24 + ( -3/24 + 18/24) = ( 16 - 3 + 18 ) / 24 = 31/24
