Answer 1

Hola! :3

Desarrollamos:

1) 9/13-(5/13+3/13)=x

9/13-8/13=x

1/13=x

2) (7/8-5/8)+10/8=y

2/8+10/8=y

12/8=y

3/2=y

3) (17/6-10/6)(3/4)=a

(7/6)(3/4)=a

(7*3)/(6*4)=a

21/24=a

7/8=a

4) 5/6+(1/3)(1/2)=b

5/6+(1*1)/(3*2)=b

5/6+1/6=b

6/6=b

1=b

5) (9/5+4/5-2/5)/(7/6-5/6)=c

(11/5)/(2/6)=c

(11/5)(6/2)=c

(11*6)/(5*2)=c

66/10=c

33/5=c

6) 7/9+(4/9)(1/4+3/4)=d

7/9+(4/9)(4/4)=d

7/9+(4/9)(1)=d

7/9+4/9=d

11/9=d

7) 8/12+(3/2)(9/6-1/6)=e

8/12+(3/2)(8/6)=e

8/12+(3*8)/(2*6)=e

8/12+24/12=e

32/12=e

8/3=e

Espero haberte ayudado :D
