Tolong menggunakan cara & harus dikumpul besok karena ini PR

1) 3/2 + 5/3 + 5/4 = 18/12 + 20/12 + 15/12 = 53/12 

2) 3/2 x 5/3 x 5/4 = 75/24 = 25/8

3) ( 3/2 x 5/3) : 5/4 = 15/6 : 5/4 = 15/6 x 4/5 = 6/3

semoga benar yaa 🙂

1. 1 1/2 + 1 2/3 + 1 1/4 = 1 6/12 + 1 8/12 + 1 3/12 = 3 17/12 = 4 5/12

2. 1 1/2 x 1 2/3 x 1 1/4 = 1 6/12 x 1 8/12 = 1 48/144 = 1 1/3 x 1 3/12 = 1 4/12 x 1 3/12 = 1 12/144 = 1 1/12

3.(1 1/2 x 1 2/3) : 1 1/4 = 1 1/2 x 1 2/3 = 1 6/12 x 1 8/12 = 1 48/144 = 1 1/3 : 1 1/4 = 1 4/12 : 1 3/12 = 1 4/12 x 1 12/3 = 1 48/36 = 1 4/3 = 2 1/3

Maaf kalo rumit dan kalo ada salah mohon maaf 🙂
Kalo caranya juga salah juga maaf
