tolong jawab pakai caranya ya

==Jawaban==

b). 0,5 + 1/3 x 25%
= 5/10 + 1/3 x 25/100
= 5/10 + 1/3 x 1/4
= 5/10 + 1/12
= 70/120
= 7/12

c).0,5 + 1/3 : 25%
= 5/10 + 1/3 : 25/100
= 5/10 + 1/3 : 1/4
= 5/10 + 1/3 x 4/1
= 5/10 + 4/3
= 55/30
= 11/6

2. 0,5 + ⅓ × 25%
→ 5/10 + ⅓ × 25/100
→ ½ + ⅓ × ¼
→ ½ + 1/12
→ 6/12 + 1/12
→ 7/12

3. 0,5 + ⅓ : 25%
→ 5/10 + ⅓ : 25/100
→ ½ + ⅓ : ¼
→ ½ + ⅓ × 4
→ ½ + 4/3
→ 3/6 + 8/6
→ 11/6
