» Soal:

1. Hitunglah bilangan berikut:

A. 3 3/5 × 2 1/3

B. 3/4 × 5

C. 2/3 × 4/5 × 3/3

» Jawab:

— Pecahan, alangkah baiknya, ubah dulu pecahan campuran menjadi pecahan biasa:

= 3 3/5

= (3 × 5 + 3)/5

= (15 + 3)/5

= 18/5

---

= 2 1/3

= (2 × 3 + 1)/3

= (6 + 1)/3

= 7/3

— lalu kalikan:

A. 3 3/5 × 2 1/3

= 18/5 × 7/3

= 126/15

= (126 ÷ 3)/(15 ÷ 3)

= 42/5

= 8 2/5 ✓

B. 3/4 × 5

= 3/4 × 5/1

= 15/4

= 3 3/4 ✓

C. 2/3 × 4/5 × 3/3

= 8/15 × 1

= 8/15 ✓

» Kesimpulan:

∴ Jadi, jawaban dari pertanyaan tersebut adalah A. {8 2/5} ; B. {3 3/4} ; C. {8/15} .
