6. 12 5/6 – 2 1/6 – 1/2 =
= 12 5/6 – 2 1/6 – 3/6
= 10 4/6 – 3/6
= 10 1/6
7. 15 9/11 + 2 1/22 – 1 1/2 =
= 15 18/22 + 1 1/22 – 1 11/22
= 16 19/22 – 1 11/22
= 15 18/22
= 15 9/11
8. 20 2/3 + 2 3/5 – 2 2/15 =
= 20 10/15 + 2 9/15 – 2 2/15
= 22 1/15 – 2 2/15
= 21 16/15 – 2 2/15
= 19 14/15
9. 24 8/9 – 12 1/6 – 3 1/2 =
= 24 16/18 – 12 3/18 – 3 9/18
= 12 13/18 – 3 9/18 = 9 4/18
= 9 2/9
10. 50 5/6 – 5 5/12 – 4 1/8 =
= 50 20/24 – 5 10/24 – 4 3/24
= 45 10/24 – 4 3/24
= 41 7/24
Soal pasangkanlah operasi hitung yang memiliki nilai sama, berikut jawabannya
1. 6 1/6 + 5 5/12 – 4 1/3
= 6 2/12 + 5 5/12 – 4 4/12
= 11 7/12 – 4 4/12
= 7 3/12
= 7 1/4
2. 5 4/5 – 2 7/10 – 1 1/4
= 5 16/20 – 2 14/20 – 1 5/20
= 3 2/20 – 1 5/20
= 2 22/20 – 1 5/20
= 1 17/20
3. 10 5/8 – 4 5/12 + 2 3/4
= 10 15/24 – 4 10/24 + 2 18/24
= 6 5/24 + 2 18/24
= 5 29/24 – 2 18/24
= 3 11/24
4. 12 5/6 + 3 1/12 – 5 1/4
= 12 10/12 + 3 1/12 – 5 3/12
= 15 11/12 – 5 3/12 = 10 8/12
= 10 2/3
5. 15 – 5 4/16 – 4 1/8
= 14 16/16 – 5 4/16 – 4 2/16
= 9 12/16 – 4 2/16
= 5 10/16
= 5 5/8
a. 1/5 + 2 = 2 1/5
b. 3 1/4 + 2 3/8
= 3 2/8 + 2 3/8
= 5 5/8
c. 9 + 5/6 = 9 5/6
