1.6.1 Nombor Nisbah, Praktis Berformat PT3 - Matematik Tingkatan 1, 2 dan 3

Soalan 1:
Hitung 8 × 2 ÷ 4 + 12.

Penyelesaian:
8 × 2 ÷ 4 + 12
= 16 ÷ 4 + 12
= 4 + 12
= 16

Soalan 2:
Hitung 7(6 + 5) – 3(13 – 9).

Penyelesaian:
7(6 + 5) – 3(13 – 9)
= 7(11) – 3(4)
= 77 – 12
= 65

Soalan 3:
Hitung 64 + (136 – 87) × (28 ÷ 4).

Penyelesaian:
64 + (136 – 87) × (28 ÷ 4)
= 64 + 49 × 7
= 64 + 343
= 407

Soalan 4:
Solve 84 ÷ 4 – 9 + 6 × 7

Penyelesaian:
84 ÷ 4 – 9 + 6 × 7
= 21 – 9 + 42
= 12 + 42
= 54

Soalan 5:
Solve 92 + 13 × 5 – 42

Penyelesaian:
92 + 13 × 5 – 42
= 92 + (13 × 5) – 42
= 92 + 65 – 42
= 157 – 42
= 115
