The number of strips of 1 9/16 inches, that can be made from 8 1/2 inches of paper is <u>5 11/25</u>.
In the question, we are given that an 8 1/2 sheet of paper is being cut into 1 9/16 inch strip to make a paper chain.
We are asked the number of strips that can be made from one sheet of paper.
The size of the paper given to us is 8 1/2.
Converting this to an improper fraction, we get 8 1/2 = 17/2.
The size of the strip given to us is 1 9/16.
Converting this to an improper fraction, we get 1 9/16 = 25/16.
To find the number of strips, we just divide the total paper's size by the size of the strip, to get:
The number of strips = 17/2 ÷ 25/16,
or, the number of strips = 17/2 * 16/25,
or, the number of strips = 272/50,
or, the number of strips = 544/100,
or, the number of strips = 5 11/25.
Thus, the number of strips of 1 9/16 inches, that can be made from 8 1/2 inches of paper is <u>5 11/25</u>.
