Tolong bantuin ngerjain pr matematika soalnya saya gak ngerti nih soalnya. 1. 18/21= 2. 9/16= 3. 39/57= 4.68/76= 5.20/32= jadikan lecahan sederh

Jawabannya:

1. 18/21
→ 6/7

2. 9/16
→ 9/16 → Karena gk bisa disederhanain lg

3. 39/57
→ 13/19

4. 68/76
→ 34/38
→ 17/19

5. 20/32
→ 10/16
→ 5/8
Atau
→ 0,625

[tex] \frac{18}{21} = \frac{18 \div 3}{21 \div 3} = \frac{6}{7} [/tex]

___________________________

[tex] \frac{9}{16} = \frac{9}{16} [/tex]

Pada pecahan ini, tidak bisa lagi disederhanakan.

___________________________

[tex] \frac{39}{57} = \frac{39 \div 3}{57 \div 3} = \frac{13}{19} [/tex]

___________________________

[tex] \frac{68}{76} = \frac{68 \div 2}{76 \div 2} = \frac{34}{38} [/tex]

[tex] \frac{34 \div 2}{38 \div 2} = \frac{17}{19} [/tex]

___________________________

[tex] \frac{20}{32} = \frac{20 \div 4}{32 \div 4} = \frac{5}{8} [/tex]
