Verified answer

Pertama -" cari kpk dari penyebut tersebut :
1. 2/6 +6/7 + 3/2 =14/42+ 36/42 +63/42= 113/42= 2 29/42 = 2 3/6
2. 4/5+2/10+4/2 = 8/10+2/10 + 20/10 = 30/10 =3
3. 3 2/3 + 4 2/2 + 2 8/3 = 11/3 + 10/2 + 14/3 = 22/6 + 30/6 + 28/6 = 80/6 = 40/3
4. 2 6/3 + 3 2/5 - 2 1/2 = 12/3 + 17/5 -5/2 = 120/30 + 102/30 - 75/30 = 147/30 = 71/15
5. 6 2/3 + 4/5 - 2/15 = 20/3 + 4/5 - 2/15 = 100/15 + 12/15 -2/15 = 110/15 = 22/3
6. 7 3/3 + 2/6 - 6 2/3 = 24/3 + 2/6 - 20/3 = 48/6 + 2/6 - 40/6 = 10/6 = 5/3
7. 3 2/8 + 6/4 + 9 3/2 = 26/8 + 6/4 - 21/2 = 26/8 + 12/8 - 48/8 = -10/8 = -5/4
jika hasil yang di minta bilangan desimal kamu langsung bagi aja pecahan terakhir.
jika ada yang kurang di mengerti silakan di tanyakan .........
semoga membantu......☺
