Hi Brittany, I have two suggestions for you, one from Chris and the other from Claude. Why not try factoring 65,125? ChrisOne number ends with 5, so the other will start with 5 and end with an odd number. The number starting with 5 will be at least 500, and 65125/500 is about 650/5 = 130, so the number ending in 5 is at most 130. This should give you an idea of which numbers to try. Claude |
