In the following three equations (1), (2), and (3), each one contains a blank. Please indicate which equation contains the blank such that $\square = 3 \frac{1}{20}$.

(1) $\left.4 \frac{1}{2} \div\left[0.4+\left(6 \frac{1}{3}-\square\right) \div 12 \frac{1}{2} \times 0.75\right]=10 \div 12 \frac{1}{2} \times 0.75\right]=10$

(2) $\frac{\left[\frac{5}{8} \times\left(2 \frac{3}{4}-1.15\right)+7.8\right] \div 8 \frac{4}{5}}{(6-\square) \div 29.5}$

(3) $\left[\left(6.5-\frac{2}{3}\right) \div 3 \frac{1}{2}-1 \frac{8}{15}\right] \times(\square+71.95)=1$.
