Answer: To find out how many pieces of yarn Melissa can make, we need to divide the total length of the yarn by the length of each individual piece.
If the piece of yarn is 12.42 centimeters long and she wants to make pieces that are 0.54 centimeters long, we can use the following formula:
Number of pieces = Total length of yarn / Length of each piece
Number of pieces = 12.42 / 0.54
Number of pieces = 23.03 pieces
Melissa can make 23 pieces of yarn with a length of 0.54 centimeters each from the 12.42 centimeters long yarn.
