Question

Elena has a piece of wire that is 36 inches long. She uses ____ of the piece of wire to make a necklace. Then, she uses ____ of the remaining wire to make a bracelet. Finally, she uses ____ of the rest of her wire to make earrings. How much of the piece of wire, in inches, does Elena have left after making the necklace, bracelet, and earrings?

1) 18
2) 9
3) 27
4) cannot be determined

Answer 1

Without the specific fractions of wire used for the necklace, bracelet, and earrings, it is impossible to determine the length of wire Elena has left. For such problems, the length of wire used for each item would typically be calculated by multiplying the total length by the provided fractions.

Step-by-step explanation:

The student's question relates to the amount of wire left after Elena makes a necklace, a bracelet, and a pair of earrings from a 36-inch piece of wire. However, the specific fractions of the original and remaining wires used for each item are not provided in the question. Therefore, without this critical information, it is impossible to determine the exact length of wire Elena has left after making the necklace, bracelet, and earrings. To solve similar problems, you normally would multiply the length of wire by the fractions provided to find the lengths used for each item, and subtract those from the total length to find the unused portion.
