8 1/2 + 1 +1/4 - 7 3/5 =…
Cara paling gampang pisahkan angka dengan pecahan.
8+1-7 = 9-7 = 2
1/2 + 1/4 - 3/5 = (KPK masing-masing penyebut adalah 20
10/20 + 5/20 - 12/20
= (10+5-12)/20 = 3/20
Jadi 2 + 3/20 = 2 3/20 m.
= 17/2 + 5/4 - 38/5
= 34/4 + 5/4 - 38/5
= 39/4 - 38/5
= 195/20 - 152/20
= 43/20
= 2 3/20
