There are 12 levels in Liangs new video game. If he plays the same number of levels each day, what are all the possibilities for the number of days he could spend playing the game without repeating a level?

For this question look for factors of 12-

These would be

1 and 12 (1 x 12 = 12)

2 and 6 (2 x 6 = 12)

3 and 4 (3 x 4 = 12)

Using that information,

Liang could either play

1 level each day for 12 days

2 levels each day for 6 days

3 levels each day for 4 days

4 levels each day for 3 days

6 levels each day for 2 days

Or ...

12 levels in one day

I'm not sure but if it's without repeating all level it could be 12 or less no more than 12 I'd say
