Kaia rewrote the sum 96 + 12 as 12 (8 + 1). She used the same method to

rewrite the sum 95 + 15 as 5 (19 + 3). Describe her method and tell whether

she can use it to rewrite the sum 38 + 11. Explain.

Kaia found a common dividend (if thats the right word), a common factor that both could be divided by, and then did the distributive property backwards pretty much, taking out that common factor from each. You can't use it on that last one because eleven is a prime number (unable to be divided by anything other than one and itself), so the two numbers won't have a common dividor number thingy.
