Tolong jawab KK 1. 36-(-4 2. 17+-(-30 3. 2per3 +1per6 4. 1per2+1per4 5. Sederhanakan 24per10 6. Sederhanakan 30per12 7. 5per7 - 1per3

1. 36--4 =36 +4 = 40
2. 17+--30 = 47
3.2/3 + 1/6 =4/6+1/6=5/6
4. 1/2+1/4 = 2/4+1/4 =3/4
5. 24/10 = 12/5
6. 30/12 = 15/6 = 5/3
7. 5/7-1/3 = 15/21 - 7/21 = 8/21

langsung aja y

1. 36 - (-4) = 36 + 4 = 40

2. 17 - (-30) = 17 + 30 = 47

3. ⅔ + 1/6 = 4/6 + 1/6 = 5/6

4. ½ + ¼ = 2/4 + ¼ = ¾

5. 24/10 = 12/5 = 2 2/5

6. 30/12 = 5/2 = 2 ½

7. 5/7 - ⅓ = 15/21 - 7/21 = 8/21

semoga berguna +_+
