Answer 1

Respuestas: a) -12 , b) 10 , c) 59/15 , d) 31/6 , e) -47/21

Explicación paso a paso:

a) (-5-2)+(-3-2)= -7 + (-5)= -12

b) (16÷4)+(9-3)= 4 + 6= 10

c) (1/5+7/5)-(4/3-11/3)= 8/5-(-7/3)= 8/5 + 7/3= (3x8 +35)/15= 59/15

d) (15-10)+(1/2-1/3)= 5 + (3-2)/6= 5 + 1/6= (30 +1)/6= 31/6

e) (4/7-1/7)-(2/3+6/3)= 3/7 - 8/3= (9 - 56)/21= -47/21
