What can be divided? For example, for 48 you can divide 1, and 48 and you can also divide it by two which equals to 24 so keep writing that from least to greatest. You don't have repeat answers.
1,2,3,4,6,8,12,16,24,48
2+1/3n=8 is the answer, I believe.
6*2 = 12
12/2 = 6
So, the answer could be 12/2
Will there's
5.5 x 2 = 11
hope that helped
