bentuk sederhana dari 3ab/c : 9b^2/4ac adalah..

[tex] \frac{3ab}{c} \div \frac{9b ^{2} }{4ac} \\ = \frac{3ab}{c} \times \frac{4ac}{9b ^{2} } \\ = \frac{3ab}{1} \times \frac{4a}{9b ^{2} } \\ = \frac{a}{1} \times \frac{4a}{3b} \\ = \frac{4a ^{2} }{3b} [/tex]

Maaf Kalau Salah

3ab/c : 9b^2/4ac = 3ab/c x 4ac/9b^2 = 3a x 4a/9b = 12a^2/9b
