Tolong dong ya KAK pakai CARA ya , Besok mau dikumpulin

1) gak tau
2) 3 2/5 - 3/14 = 17/5 - 3/14 =238/70 - 15/70 = 238-15/ 70 =223/70 = 3 13/70
3) 11 8/9 - 3 1/6 = 107/9 - 19/6 =856/72 - 228/72 = 856-228/72 = 628/72 = 8 52/72 = 8 26/36 = 8 13/18
4) 3 1/3 + 2 ½ + ¾ = 10/3 + 5/2 +¾ =40/12 + 30/12 + 9/12 = 40+30+9/12 =79/12 = 6 7/12
5) 2 ¼ + 3 2/6 = 9/4 + 20/6 = 54/24 = 80/24 = 54+80/24 = 134/24 = 5 14/24 = 5 7/12

Itu jawabannya semoga membantu.
