Answer:
[tex]x \div \frac{3}{7} = \frac{7}{15} \\ x = \frac{7}{15} \div \frac{7}{3} \\ x = \frac{7}{15} \times \frac{3}{7} = \frac{1}{5} \\ x = \frac{1}{5} \\ now \: \: lets \: \: see \: whether \: \: this \: \: correct \\ \frac{1}{5} \div \frac{3}{7} \\ \frac{1}{5} \times \frac{7}{3} = \frac{7}{15} [/tex]
