Penjelasan dengan langkah-langkah:

[tex]\dfrac{ 5 }{ 8 } + \dfrac{ 7 }{ 9 } \times \dfrac{ 15 }{ 6 } - \dfrac{ 18 }{ 6 } \\ \\ = \frac{5}{8} + \frac{7}{9} \times \frac{15 \div 3}{6 \div 3} - \frac{18 \div 6}{6 \div 6} \\ \\ = \frac{5}{8} + \frac{7}{9} \times \frac{5}{2} - 3 \\ \\ = \frac{5}{8} + \frac{35}{18} - 3 \\ \\ = \frac{45}{72} + \frac{140}{72} - \frac{216}{72} \\ \\ = \frac{45 + 140 - 216}{72} \\ \\ = \frac{185 - 216}{72} \\ \\ = - \frac{31}{72} [/tex]
