Jawaban:
1. 20 + (-4×5) -7
= 20 + -20 - 7
= -7
2. 3,6 - 1 ⅔ + 0,2
= 36/10 - 5/3 + 2/10
= 108/30 - 50/30 + 6/10
= 64/30
= 2 4/30 = 2 2/15
3. 4,3 × 1,2 = 5,16 ____ cara terlampir
4. 0,4 × 2,1 = 0,84 ____ cara terlampir
5. 3,3 : 1,5 = 2,2
6. 1/5 + 2/3
= 3/15 + 10/15
= 13/15
7. 3/4 - 1/5
= 15/20 - 4/20
= 11/20
8. 8/7 + 0,5
= 8/7 + 5/10
= 80/70 + 30/70
= 110/70
= 1 40/70
= 1 4/7
9. 2 ¼ - 1,5
= 9/4 - 15/10
= 90/40 - 60/40
= 30/40
= 3/4
10. 1,34 + 2,5 - ¼
= 134/100 + 25/10 - ¼
= 134/100 + 250/100 - 25/100
= 359/100
= 3 59/100
