Answer 1

Odpowiedź:

zadanie 2.

a)

3/5 + 7/10 = 6/10 + 7/10 = 13/10 = 1 i 3/10

4/5 - 4/15 = 12/15 - 4/15= 8/15

11/30 + 1/6 = 11/30 + 5/30 = 16/30 = 8/15

b)

2 - 5/11 = 1 i 11/11 - 5/11= 1 i 6/11

8 - 1 i 3/4 = 7 i 4/4 - 1 i 3/4 = 6 i 1/4

12 - 4 i 1/9 = 11 i 9/9 - 4 i 1/9 = 7 i 8/9

c)

2 i 4/7 - 1 i 1/2 = 2 i 8/14 - 1 i 7/14= 1 i 1/14

12 i 2/3 + 1 i 3/4 = 12 i 8/12 + 1 i 9/12 = 13 i 17/12= 14 i 5/12

8 i 1/8 - 2/3 = 8 i 3/24 - 16/24 = 7 i 27/24 - 16/24 = 7 i 11/24

d)

6 i 1/4 - 3 i 5/6 = 6 i 3/12 - 3 i 10/12= 5 i 15/12 - 3 i 10/12= 2 i 5/12

7 i 1/6 + 6 i 1/8 = 7 i 4/24 +6 i 3/24= 13 i 7/24

6 i 1/3 - 3 i 5/6 = 6 i 2/6 - 3 i 5/6 = 5 i 8/6 - 3 i 5/6= 2 i 3/6 = 2 i 1/2
