Answer:
Step-by-step explanation:
[tex]2.4 \div -1/5\\\\= \frac{2.4}{-\frac{1}{5}}\\\\\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{-b}=-\frac{a}{b}\\\\=-\frac{2.4}{\frac{1}{5}}\\\\\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{\frac{b}{c}}=\frac{a\times\:c}{b}\\\frac{2.4}{\frac{1}{5}}=\frac{2.4\times\:5}{1}\\\\=-\frac{2.4\times\:5}{1}\\\\\mathrm{Multiply\:the\:numbers:}\:2.4\times\:5=12\\\\=-\frac{12}{1}\\\\=-12[/tex]
