poizon [28]

Answer:

Each strip should 11 inches wide.

Step-by-step explanation:

We are told that Jazmin has two pieces of construction paper. The first piece is 44 inches wide and the second piece is 33 inches wide. Jazmin wants to cut the paper into strips that are equal in width and are as wide as possible.

To find the greatest possible width of each strip we will find GCF of 44 and 33.

Factors of 44 are: 1, 2, 4, 11, 22, 44.

Factors of 33 are: 1, 3,11, 33.

We can see that 11 is the greatest common factor of 44 and 33 as 11*4=44 and 11*3=33, therefore, Jasmine should cut each strip 11 inches wide.
