Answer:
3/14
Step-by-step explanation:
[tex]We\ can\ solve\ the\ following\ problem\ through\ distributive\ property,\\Here,\\\frac{1}{7} /\frac{2}{5} -\frac{1}{7} \\=\frac{1}{7}*\frac{1}{\frac{2}{5} } -\frac{1}{7} \\=\frac{1}{7}*\frac{5}{2}-\frac{1}{7} \\=\frac{1}{7}[\frac{5}{2}-1]\\=\frac{1}{7}[\frac{5}{2} -\frac{2}{2}]\\=\frac{1}{7}*\frac{3}{2}\\=\frac{3}{14}[/tex]
