Jawaban:
_____________ ______________
2/7 - 5/14 1/6 - (- 1/2)
= 4/14 - 5/14 = 1/6 - (- 3/6)
= - 1/14 = 4/6
= 2/3
_____________ ______________
- 1/2 + (- 3/2) 1/4 + (- 5/6)
= - 4/2 = 3/12 + (- 10/12)
= - 2 = - 7/12
_______________________________
- 1/3 + 1/6 - (- 2/3)
= - 2/6 + 1/6 - (- 4/6)
= - 1/6 - (- 4/6)
= 3/6
= 1/2
_____________ ______________
0,3 + 2 1,4 + (- 0,9)
= 2,3 = 1,4 - 0,9
= 0,5
_____________ ______________
- 2,7 - (- 3,4) - 1 - 0,8
= - 2,7 + 3,4 = - 0,2
= - 0, 7
________________________________
- 0,75 - (- 3/4)
= - 3/4 - (-3/4)
= 0
