Jawaban:
________________________________
1. [tex] - 2,4 \div ( - 0.6) \times 3 \\ = - \frac{12}{5} \div( - \frac{3 }{5} ) \times 3 \\ = - \frac{12 }{5} \times ( - \frac{5}{3} ) \times 3 \\ = 4 \times 3 \\ = 12[/tex]
________________________________
2. [tex] \frac{7}{12} - \frac{4}{9} - ( - \frac{5}{18} ) \\ = \frac{21}{36} - \frac{16}{36} - ( - \frac{10}{36} ) \\ = \frac{15}{36} \\ = \frac{5}{12} [/tex]
________________________________
5. [tex] \frac{5}{14} + \frac{6}{7} \times \frac{1}{3} \\ = \frac{5}{14} + \frac{6}{21} \\ = \frac{15}{42} + \frac{12}{42} \\ = \frac{27}{42} \\ = \frac{9}{14} [/tex]
