quien me puede ayudar en esta tarea por favor ​

Answer 1

Explicación paso a paso:

A1. 1/4 + 5/6= 13/12

2. 1/6+9/10= 16/15

3. 5/6+2/5= 37/30

4. 5/8+1/6+2/3

19/24+2/3=35/24

B1. (-1/3)+(-1/6)

-1/3-1/6= -1/2

2. (-7/9)+(-1/3)

-7/9-1/3= -10/9

3. (-1/4)+(-5/12)

-1/4-5/12= -2/3

4. (-2/10)+(-7/100)

-2/10-7/100= -27/100

C5. 7/8+(-1/2)

7/8-1/2= 3/8

6.(-1/9)+5/6

-1/9+5/6= 13/18

7. (-1/4)+3/10

-1/4+3/10= 1/20

8. 3/4+1/2+1/6

5/4+1/6= 17/12

9. 3/8+1/3+(-3/4)

17/24-3/4= -1/24

10.1/2+(-1/4)+(-3/5)

1/2-1/4-3/5

1/4-3/5= -7/20

D11. 11/15-7/10=1/30

12.7/9-5/6= -1/18

13. (-5/6)-(-1/2)

-5/6+1/2= -1/3

14.(-5/12)-(-4/6)

-5/12+4/6= 1/4

15.1/2+(-3/4)-2/3

1/2-3/4-2/3

-1/4-2/3= -11/12

16. (-2/7)-(-3/6)+(-5/3)

-2/7+3/6-5/3

3/14-5/3= -61/42

E17.14.07+17=31.07

18. 24.052

19. 3.515+734.2=737.715

20. 0.677

21. 153.08

22. 2.12+29.6-0.387

31.72-0.387=31.333
