Question

me podrían ayudar por favor
1. Una suma de fracciones homogéneas
5/6 + 6/6 =
8/7 + 9/7 =
15/6 + 16/6 =
10/11 + 14/11 =
20/12 + 4/12 =
9/8 + 9/8 =
17/30 + 13/30 =
2/4 + 2/4 =
13/2 + 13/2 =
2. Resta de fracciones homogéneas.
6/6 - 5/6 =
15/12 - 6/12 =
20/14 - 10/14 =
30/19 - 23/19 =
40/6 - 25/6 =
14/5 - 13/5 =
19/2 - 9/2 =
4/4 - 1/4 =
33/7 - 3/7 =

Answer 1

Respuesta:

5/6 + 6/6 = 5+6 = 11/6

                    6

8/7 + 9/7 = 17/7

15/6 + 16/6 = 31/6

10/11 + 14/11 = 24/11

20/12 + 4/12 = 24/12 = 12/6 = 6/3 = 2/1 = 2

9/8 + 9/8 = 18/8 = 9/4

17/30 + 13/30 = 30/30 = 1

2/4 + 2/4 = 4/4 = 1

13/2 + 13/2 = 26/2 = 13/1 = 13

-----------------------------------------

6/6 - 5/6 = 1/6

15/12 - 6/12 = 9/12 = 3/4

20/14 - 10/14 = 10/14 = 5/7

30/19 - 23/19 = 7/19
