7/14 ÷ 1 1/2 × 9/15 jadi br

[tex] \frac{7}{14} \div \frac{3}{2} \times \frac{9}{15} \\ = \frac{7}{14} \times \frac{2}{3} \times \frac{9}{15} \\ = \frac{126( \div 6)}{630( \div 6)} = \frac{21( \div 3)}{105( \div 3)} = \frac{7( \div 7)}{35( \div 7)} \\ = \frac{1}{5} [/tex]



Maaf Kalau Salah hehe

[tex] \frac{7}{14} \div \frac{11}{2} \times \frac{9}{15} \\ = \frac{7}{14} \times \frac{2}{11} \times \frac{9}{15} \\ = \frac{21}{385} \\ = \frac{3}{55} [/tex]
