c.- 3/6 + 1/3 - 2/5 - 4/7 =
d.- 9/6 + 4/5 - 4/3 =
e.- 6/5 + 5/7 - 2/9 =

Answer 1

Respuesta:

Explicación paso a paso:

a.-2/7 + 1/7 - 3/7 = (-2 + 1 - 3)/7 = -4/7

b. -7/3 - 2/3 + 1/3 = (-7 -2 + 1)/3 = -8/3

c.- 3/6 + 1/3 - 2/5 - 4/7 = (-105  + 70 - 84 - 120)/210 = -239/210

d.- 9/6 + 4/5 - 4/3 = (-45 + 24 - 40)/30 = -61/30

e.- 6/5 + 5/7 - 2/9 = (-42 + 25)/35 - 2/9 = -17/35 - 2/9 = (-153 - 70)/315 = -223/315
