8 3/2+3 1/2-2 1/4 pakai jalan nya

8   3/2 = 19/2
3   1/2 = 7/2
2   1/4 = 9/4
jadi :
(19/2 + 7/2) - 9/4
= (26/2) -9/4
= 13 -9/4
=(13(4) - 9)/4
=(52-9)/4
= 43/4
= 10   3/4

ubah jadi pecahan biasa
8 3/2 = 19/2
3 1/2 = 7/2
2 1/4 = 9/4

19/2 + 7/2 = 26/2

26/2 - 9/4 = samakan penyebutnya = 52/4 - 9/4 = 43/4

semoga membantu ^^
