Perhatikan penjelasan berikut ya.

Ingat kembali:
→ a b/c = (a x c + b) / c
→ jika ada 1 angka di belakang koma, maka pecahan berpenyebut 10
→ jika aa/b + c/d maka samakan penyebut terlebih dahulu dengan mencari KPK dari b dan d
→ a/c + b/c = (a + b) / c
→ a + b/c = a b/c

Hasil dari 4 1/3 + 2 1/2 + 1,5 dapat ditentukan sebagai berikut:

4 1/3 + 2 1/2 + 1,5
= [(4 x 3 + 1) / 3] + [(2 x 2 + 1) / 2] + 15/10
= 13/3 + 5/2 + [(15 : 5) / (10 : 5)] = 13/3 + 5/2 + 3/2
= 13/3 + [(5 + 3) / 2] = 13/3 + 8/2
= 13/3 + 4
= 4 13/3
= (4 x 3 + 13) / 3
= 25/3
= 24/3 + 1/3
= 8 + 1/3
= 8 1/3

Sehingga: 4 1/3 + 2 1/2 1,5 = 8 1/3.

Jadi, jawaban yang benar adalah 8 1/3 (tidak ada pilihan jawaban yang sesuai).
