N would be 3. [tex] \leq [/tex] means the one on the left is the same as, or less than the one on the right. The one on the right is 21. N would be 3 because 7 x 3 = 21. Therefore 7n is the same as 21. 7 x 3 = 21. N=3.

3 because 3x7 = 21 which is equal to 21
2 because  7x2 = 14 which is less than 21
and i believe the last one could be 1 because 1x7 = 7 which is less than 21
