Chester needs 2 feet of ribbon for an art project, but his ruler only measures in centimeters. There are 12 inches in 1 foot and 2.54 centimeters in 1 inch.
Chester multiplied 12 by 2 and then divided the product by 2.54 to find that he needs about
9.4 centimeters of ribbon. This length is much shorter than 2 feet, so he knows he is incorrect.
Which of these would give Chester the correct number of centimeters of ribbon he needs?
