Answer 1

$- 2.6x = - 10.4 \\ x = - 10.4 \div ( - 2.6) \\ x = 4$

$- 10.15 \div x = 3.5 \\ x = - 10.15 \div 3.5 \\ x = - 101.5 \div 35 \\ x = - 2.9$

$3.7x = - 9.62 \\ x = - 9.62 \div 3.7 \\ - 96.2 \div 37 \\ x = - 2.6$

$- 9.86 \div x = - 3.4 \\ x = - 9.86 \div ( - 3.4) \\ x = - 98.6 \div ( - 34) \\ x = 2.9$

$- \frac{8}{9} x = - \frac{16}{27} \\ x = - \frac{16}{27} \div ( - \frac{8}{9} ) \\ x = \frac{16 \times 9}{27 \times 8} \\ x = \frac{2}{3}$

$- \frac{10}{13} \div x = 5 \\ x = - \frac{10}{13} \div 5 \\ x = - \frac{10}{13 \times 5} \\ x = - \frac{2}{13}$

$\frac{4}{7} x = - 1 \frac{11}{21} \\ x = - 1\frac{11}{21} \div \frac{4}{7} \\ x = - \frac{32 \times 7}{21 \times 4} \\ x = - \frac{8}{3} \\ x = - 2 \frac{2}{3}$

$- 3 \frac{3}{4} \div x = - 11 \frac{1}{4} \\ x = - 3 \frac{3}{4} \div ( - 11 \frac{1}{4} ) \\ x = \frac{15 \div 4}{4 \div 45} \\ x = \frac{1}{3}$
