Yes. Since 3 is a factor of 9, anything 9 can go into, 3 can also go into.
3x3=9
So, whenever 9 can go into something, it will take 3 times as many 3s to go into that number.
Example:
3 nines = 27
9 threes = 27
9 is 3 times as many as 9.
To sum everything up, Gerri is correct. This is because 3 is a factor (goes into 9 evenly) of 9.
(I don’t think I did too great of a job explaining, but you just need the last paragraph, the example was just there for reference)
