Jawaban:
[tex]-34 \frac{23}{30} [/tex]
Penjelasan dengan langkah-langkah:
[tex](4 \frac{1}{5} \times ( - 6 \frac{3}{7} )) + (5 \frac{5}{8} \div 2 \frac{1}{12} ) - 10 \frac{7}{15} \\ = ( \frac{21}{5} \times ( - \frac{45}{7} )) + ( \frac{45}{8} \div \frac{25}{12} ) - \frac{157}{15} \\ = - 27 + ( \frac{45}{8} \times \frac{12}{25} ) - \frac{157}{15} \\ = - 27 + \frac{27}{10} - \frac{157}{15} \\ = - \frac{810}{30} + \frac{81}{30} - \frac{314}{30} \\ = - \frac{1043}{30} \\ = - 34 \frac{23}{30} [/tex]
