Test if 8 is divisible by all possible numbers. Start by testing the smallest number possible (1) and making your way up to the largest number possible (7). 8/1= 8 8/2=4 8/3= not a whole number 8/4 = 2 8/5 = not a whole number 8/6 = not a whole number 8/7 = not a whole number note we did not try 8/8 because that would not be considered "taking apart". After sorting out our test answers we can conclude that you can take 8 apart in three ways. In 8 groups of 1, in 2 groups of 4, and in 4 groups of 2. You can show this in pictures by illustrating these groups. See Below x x x x x x x x xx xx xx xx xxxx xxxx
