Find the sum of 301+73+27, mentally, using the associative property of addition. show how you can use the property to group two of the addends. explain how you found the sum.

The answer is 401, because you can put parenthesis between 73 and 27. The equation would now be 301+(73+27). You do the expression inside the parentheses first. Now it will be 301+(100) which is the same as 301+100. You know 301 plus 100, which is 401. There's your answer. I hope this helped.

This is too long-standing now get out
