Lance wants to find the total length of 3 boards. he uses the expression 3 1/2+( 2+4 1/2 how can lance rewrite the expression using both the associative and commutive properties of addition

Step-by-step explanation:

This problem bothers on the use of mathematical properties

Given the expression

3 1/2+( 2+4 1/2)

Applying the associative property rule which says we can add or multiply regardless of how numbers are grouped

Associative property

3 1/2+( 2+4 1/2) can re re-written as

(3 1/2+2) +4 1/2

Commutative property

This rule states that the we can move (commute) figures about and still get same result.

Hence 3 1/2+( 2+4 1/2) can also be expressed as (2+4 1/2+3 1/2)

Or (4 1/2 +2+ 3 1/2)

because its not ur topic and its not for is for homework not that.
