Operasi hitung pecahan
- 2 2/7 : 10/5 + 3/9 = 1 10/21
- 3,6 : 4/5 + 1,5 = 6
- 2/7 : 5/14 + 1 1/2 = 1 9/10
- 13 1/2 : 0,5 + 18 = 45
- 2 2/3 + 0,25 - 1 3/4 × 1,6 = 7/60
1. 2 2/7 : 10/5 + 3/9 = 16/7 × 5/10 + 1/3
= 8/7 + 1/3
= 24/21 + 7/21
= 31/21
= 1 10/21
2. 3,6 : 4/5 + 1,5 = 36/10 × 5/4 + 15/10
= 9/2 + 15/10
= 45/10 + 15/10
= 60/10
= 6
3. 2/7 : 5/14 + 1 1/2 = 2/7 × 14/5 + 1 1/2
= 2/5 + 1 1/2
= 4/10 + 1 5/10
= 1 9/10
4. 13 1/2 : 0,5 + 18 = 27/2 : 5/10 + 18
= 27/2 × 10/5 + 18
= 27 + 18
= 45
5. 2 2/3 + 0,25 - 1 3/4 × 1,6
= 2 2/3 + 1/4 - (7/4 × 16/10)
= 2 8/12 + 3/12 - 14/5
= 2 11/12 - 14/5
= 35/12 - 14/5
= 175/60 - 168/60
= 7/60
