Tina is joining 3 sections of a quilt. Each section has 3 rows of 15 square pieces of fabric. How many squares will be in the complete quilt? Does the product change if you change the grouping of factors? Explain

There will be 135 squares in total. Changing the order of the factors wont change the result.

Step-by-step explanation:

(i am assuming that sqaures = sqaure pieces)

Each section has 3 rows of 15 square pieces, therefore each section has 3*15 = 45 sqaure pieces. Thus, the complete guilt will have 45*3 = 135 square pieces. Since all we do were multiplications, changing the order of the factors wont change the value of the product.
