7.1. In the record $\frac{1}{4} \frac{1}{4} \frac{1}{4} \frac{1}{4}$, insert operation signs and, if necessary, parentheses so that the value of the resulting expression equals 2.
Answer: for example, $\frac{1}{4}: \frac{1}{4}+\frac{1}{4}: \frac{1}{4}=2$ or $\frac{1}{4}:\left(\frac{1}{4}+\frac{1}{4}\right): \frac{1}{4}=2$.
