Lars bought 3 jars of marbles. Each jar has 42 marbles, of which 13 are red. Lars can use the calculation below to find the total number of red marbles.

3×(13×42)

How can Lars simplify the calculation using only the associative property of multiplication?
a1/3 b 3 c 42​​ d ​(3×13) e​​​ ​(13×42)

d. (3 x 13) x 42

is your answer

just change the parenthesis from (13 x 42) to (3 x 13), since you will still get the same answer (using associative property of multiplication)

hope this helps :D
