7. 6: 1 adalah.. 8. Pecahan campuran dari 28 adalah. 9. 2 +3 3-2 ie n, n adalah..

7. 6 : 9/5 =
6 × 5/9 *dibalik
= 10/3 = 3 ⅓

8. Pecahan campuran dari 28/5 =
5 3/5

9.3/5 + 3 ¼ - 2 ⅓ =
3/5 + 13/4 - 7/3
36 + 195 - 140 / 60
91/60
= 1 31/60


Semoga membantu ^^
Maaf kalau salah

7. 6 : 9/5
= 6/1 : 9/5
= 6/1 x 5/9
= 30/9
= 10/3
= 3 1/3

8. pecahan campuran 28/5
= 5 3/5

9. 3/5 + 3 1/4 - 2 1/3
= 3/5 + 13/4 - 7/3
    Ingat KABATAKU
3/5 + 13/4
= 12+65/20
= 77/20
77/20 - 7/3
= 231-140/60
= 91/60
= 1 31/60

Semoga Membantu dan Selamat Belajar ^_^
