At the end of the quarter, Vovochka wrote down his current grades for singing in a row and placed a multiplication sign between some of them. The product of the resulting numbers turned out to be 2007. What grade does Vovochka get for singing in the quarter? ("Kol" is not given by the singing teacher.)

#
$2007=3 \cdot 3 \cdot 223=9 \cdot 223=3 \cdot 669$. Since there is no grade 9, only the first option fits. Since Vovochka has more threes than twos, and the last grade, no matter how you rearrange the factors, is a three, we can hope that he will get a three for the quarter.

## Answer

Three.
