Jawaban :
1. = 5 1/2 - 2 1/4
= 5 2/4 - 2 1/4
= 3 ¼
2. = 45% + 2/5
= 9/20 + 2/5
= 9/20 + 8/20
= 17/20 atau 85%
3. = 0,85 - 1/2
= 17/20 - 1/2
= 17/20 - 10/20
= 7/20 atau 0,35
4. = 6 2/12
Karena : 8 2/6 + 6 2/12
: 8 4/12 + 6 2/12
: 14 6/12
Disederhanakan : 14 1/2
5. = 0,345 + 0,09 - 0,2
= 0,235
6. = 12,34 - 9,5
= 2,84
7. = 76,2 + 0,65
= 76,85
8. = 3 4/5 + 1/4
= 3 16/20 + 5/20
= 3 21/20
= 4 1/20
9. = 3 4/6 - 1/4 + 1 1/3
= 3 8/12 - 3/12 + 1 4/12
= 4 9/12
10. = 22,682
Karena : 46,71 - 22,682
: 24,028
