Anais bought 2 1/2 yards of ribbon. She had 1 feet 6 inches of ribbon left after trimming some curtains. How many inches of ribbon did Anais use to trim the curtains?

72 inches of ribbon was used

1/2

To find the number of inches of ribbon Anais used to trim the curtains, we need to first convert the yards of ribbon to inches.

1 yard is equal to 3 feet, so 2 1/2 yards is equal to (2 * 3) + (1/2 * 3) = 6 + 1.5 = 7.5 feet.

Next, we need to convert the remaining ribbon in feet and inches to inches only.

1 foot is equal to 12 inches, so 1 feet 6 inches is equal to (1 * 12) + 6 = 18 inches.

Now, we can calculate the amount of ribbon used to trim the curtains by subtracting the remaining ribbon from the total ribbon purchased:

Total ribbon purchased - Remaining ribbon = Ribbon used to trim curtains
7.5 feet * 12 inches/foot - 18 inches = Ribbon used to trim curtains
90 inches - 18 inches = Ribbon used to trim curtains
72 inches

Therefore, Anais used 72 inches of ribbon to trim the curtains.
