21). A

22). C

Penjelasan dengan langkah-langkah:

Nomor 21

Sisa = Kacang awal + Kacang yg dibeli lagi - Kacang yang digunakan

Sisa = 7 3/4 + 2/5 - 6 1/4

Sisa = 31/4 + 2/5 - 25/4

Sisa = 155/20 + 8/20 - 125/20

Sisa = 163/20 - 125/20

Sisa = 36/20

Sisa = 1 16/20

Sisa = 1 4/5 [ Opsi A ]

Jadi, kacang tanah bu Imron masih 1 4/5 kg.

Nomor 21

6,5 × 4/5 : 2 1/2

= [ 65/10 × 4/5 ] : 5/2

= 260/50 : 5/2

= 260/50 × 2/5

= 520/250

= 2 20/250

= 2 2/25 [ Opsi C ]

Nilai n adalah 2 2/25.
