Hey! I need some help with this problem (3.2m+0.7) + (2.7m+1.8).Our teacher just thought us this and she wasn't clear

Question

This is the distributive property w/decimals

Answer 1

The distributive property is not demonstrated here. Using associative and commutative properties:

(3.2m + 0.7) + (2.7m + 1.8)

3.2m + (0.7 + 2.7m) + 1.8

3.2m + (2.7m + 0.7) + 1.8

(3.2m + 2.7m) + (0.7 + 1.8)

 

Can you combine like terms
