There is an equation with all integers in the upper squares, and the answer on the right side is only the approximation of $$\frac{\square }{3}+\frac{\square }{5}+\frac{\square }{7}\approx 1.16$$ after rounding off. The numbers in each of the three upper squares of the equation are~\uline{~~~~~~~~~~}~in order. 
1. $1,2,3$ 
2. $1,3,5$ 
3. $1,4,3$
