Hitunglah.
1. (-2,7) – (-3,4)
2. (-1) – (+0,8)
3. (1/5) – (-4/5)
4. (-3/4) – (-1/2)
5. (-0,75) – (-3/4)
6. (-7/4) – (+0,4)
Pembahasan:
1. (-2,7) – (-3,4) = -2,7 + 3,4 = +0,7
2. (-1) – (+0,8) = -1 – 0,8 = -1,8
3. (1/5) – (-4/5) = 1/5 + 4/5 = 5/5 = 1
4. (-3/4) – (-1/2) = -3/4 + 2/4 = -1/4
5. (-0,75) – (-3/4) = -0,75 + 0,75 = 0
6. (-7/4) – (+0,4) = -7/4 – 2/5 = -35/20 – 8/20 = -43/20
