15. 51/10

16. 115/154

17. 64/81

18. 153/30

Explicación paso a paso:

1. 1/2- 3/8 -5/8 = le saco M.C.M.

4/8 - 3/8 - 5/8 = -4/8 = -1/2

2. 3/4 +3/8+ 4/6 = le saco M.C.M.

18/24 + 9/24 + 16/24 = 43/24

3. -3 2/5 - 4 2/4 - 1 1/8 =

-17/5 - 18/4 - 9/8 = le saco M.C.M

-136/40 - 180/40 - 45/40 = -361/40

4. 2 1/2 + 3 1/3 + 4 1/4 =

5/2 + 10/3 + 17/4 =le saco M.C.M

30/12 + 40/12 + 51/12 = 121/12

5. 12/33 • 5 2/4 =

12/33 • 22/4 = 264/132 = 44/22 = 22/11

6. 12/20 • 30/8 = 360/160 = 45/20

7. 3 7/8 × 4 1/2 =

31/7 × 9/2= 279/14

8. 7 2/3 × 5 1/3 =

23/3 × 15/3 = 345/9

9. 6/8×2/5 = 12/40

10. 4 1/2 • 1 1/2 =

9/2 • 3/2 = 27/4

11. 4 • 3/4 = 12/4

12. 5 2/4 ÷ 12/33 =

22/4 ÷ 12/33 =

22/4 × 33/12 = 726/48

13. 1 1/2 ÷ 4 2/4 =

3/2 ÷ 18/4 =

3/2 × 4/18 = 12/36

14. 5 1/2 ÷ 4 1/2 =

11/2 ÷ 9/2 =

11/2 × 2/9 = 22/18

15. 8 1/2 ÷ 1 2/3 =

17/2 ÷ 5/3 =

17/2 × 3/5 = 51/10

16. 3 2/7 ÷ 6 2/5 =

23/7 ÷ 32/5 =

23/7 × 5/22 = 115/154

17. 5 1/3 ÷ 6 3/4=

16/3 ÷ 27/4 =

16/3 × 4/27 = 64/81

18. 7 9/6 ÷ 1 2/3 =

51/6 ÷ 5/3 =

51/6 × 3/5 = 153/30

coronita, porfavor
