Question

How do you represent describe and compare additive and multiplicative relationships

Answer 1

Additive Relationships
(a+b)+c=a+(b+c) associative property of addition
can also be a+b = b+a

Multiplicative Relations
a*(b+c)=ab+ac  distributive property of multiplication

a times 1=a identity property of 1

a times 0=0

(a*b)*c=a*(b*c)

I hope this helps! 

Answer 2

To find the number of electoral votes in part A of the Explore, add 2 to the number of representatives. We call this an additive relationship. To find the number of DVDs Frannie has ordered after a given number of months, multiply the number of months by 3. We call this a multiplicative relationship.
