Fangfang's solution process for a question in the exam is as follows:  
Calculate: $\frac{1}{60}÷(\frac{2}{3}-\frac{1}{5}-\frac{2}{5})$  
Solution:  
Original expression $=\frac{1}{60}÷\frac{2}{3}-\frac{1}{60}÷\frac{1}{10}-\frac{1}{60}÷\frac{2}{5}$  
$=\frac{1}{60}×\frac{3}{2}-\frac{1}{60}×10-\frac{1}{60}×\frac{5}{2}$  
$=\frac{1}{40}-\frac{1}{6}-\frac{1}{24}$  
$=-\frac{11}{60}$  
Please determine if Fangfang's solution process is correct. If correct, explain the arithmetic laws used in the solution process; if incorrect, provide the reason and write out the correct solution process.
