Bentuk pecahan sederhana dari

→ 15 / 45
= (15 : 15) / (45 : 15)
= 1/3

→ 21 / 49
= (21 : 7) / (49 : 7)
= 3/7

→ 8 / 20
= (8 : 4) / (20 : 4)
= 2/5

→ 30 / 48
= (30 : 6) / (48 : 6)
= 5/8

→ 45 / 165
= (45 : 15) / (165 : 15)
= 3 / 11

[tex] \frac{15 \div 15}{45 \div 15} = \frac{1}{3} \\ \frac{21 \div 7}{49 \div 7} = \frac{3}{7} \\ \frac{8 \div 4}{20 \div 4} = \frac{2}{5} \\ \frac{30 \div 6}{48 \div6 } = \frac{5 \div }{8} \\ \frac{45 \div 5}{165 \div 5} = \frac{9 \div 3}{33 \div 3} = \frac{3}{11} [/tex]
