Question

Oblicz :

3 1/3 - 2 2/3 =

16 - (2 1/2 + 3 1/2) =

16 2/5 - 5 3/5 =

2 1/7 - 1 6/7 =

2 4/9 + ( 10 2/3 - 9 ) =

12 1/2 + ( 6 - 5 4/12 ) =

6 2/9 + ( 10 1/9- 2 4/9 ) =

Answer 1

3 1/3 - 2 2/3 = 2 4/3 - 2 2/3=2/3

16 - (2 1/2 + 3 1/2) = 16 - 6 = 10

16 2/5 - 5 3/5= 15 7/5 - 5 3/5 = 10 4/5

2 1/7 - 1 6/7 = 1 8/7 - 1 6/7 = 2/7

2 4/9 + ( 10 2/3 - 9) = 2 4/9 + 1 2/3 = 2 4/9 + 1 6/9 = 3 10/9 = 4 1/9

12 1/2 + ( 6 - 5 4/12 ) = 12 1/2 + 8/12 = 12 6/12 + 8/12 = 12 14/12 = 13 2/12 = 13 1/6

6 2/9 + ( 10 1/9 - 2 4/9 ) = 6 2/9 + ( 9 10/9 - 2 4/9 ) = 6 2/9 + 7 6/9 = 13 8/9
