Kak tlong di bantu ya pengurangan pecahan campuran (1). 8 7/9 - 4 1/3 =....... (2). 8 3/8 - 7 3/4 =..... Harap pakai cara ya kak

1.
8 7/9 - 4 1/3 = 79/9 - 13/3
=79/9 - 39/9
= 60/9
= 20/3
= 6 2/3

2.
8 3/8 - 7 3/4=
67/8 - 31/4 = 67/8 - 62/8
= 5/8

1. 8 7/9 - 4 1/3 = 79/9 - 13/3
=79/9 - 39/9 = 40/9 = 4 4/9 atau bisa langsung dengan menyamakan penyebut 8 7/9- 4 3/9 = 4 4/9

2. 8 3/8 - 7 3/4= 67/8 - 31/4 = 67/8 - 62/8
= 5/8
