1. Hitunglah nilai dari 3 3/5 × (-6) : (-4 4/5) 2. Nilai a yg memenuhi persamaan 2(3a + 1/4) = 5(2a - 1/6)

[tex]3 \frac{3}{5} \times ( - 6) \div ( - 4 \frac{4}{5} ) = > \frac{18}{5} \times - 6 \times ( \frac{ - 5}{20} = [/tex]
[tex] - \frac{9}{10} \times - 6 = > 5.4[/tex]



[tex]6a + \frac{1}{2} = 10a - \frac{5}{6} = \frac{1}{2} + \frac{5}{6} = 10a - 6a = > \frac{3}{6} + \frac{5}{6} = 4a = > \frac{8}{6} = 4a = > 4x \frac{6}{8} = x = > 3[/tex]
