Question

hola me podrian ayudar ​

Answer 1

Respuesta:

a=11/6

b=1/2

c=1/3

*)(a+b)×c=[(11/6)+(1/2)]×1/3=[11+3/6]×1/3

=14/6×1/3=14/18=7/9

*)(a+c)×(b-c)=[(11/6)+(1/3)]×[(1/2)-(1/3)]

=[(11+2)/6]×[(3-2)/6]=(13/6)×(1/6)=13/36

×)(a+b-c)÷(a-b)=[(11/6)+(1/2)-(1/3)]÷[(11/6)-(1/2)]

=(12/6)÷(11-3/6)=2÷(8/6)=2/1÷4/3=6/4=3/2
