Andrea has a strip of fabric that is 8 2/5 feet long. how many 2 1/10- foot pieces can she cut from this fabric.
To find the number of 2 1/10-foot pieces Andrea can cut from the fabric, we need to divide the total length of the fabric by the length of each piece.
Convert the length of the fabric to an improper fraction:
8 2/5 = (5 * 8 + 2)/5 = 42/5.
Convert 2 1/10 to an improper fraction:
2 1/10 = (10 * 2 + 1)/10 = 21/10.
Divide 42/5 by 21/10:
(42/5) รท (21/10)
= (42/5) * (10/21)
= (42 * 10) / (5 * 21)
= 420/105
= 4.
Therefore, Andrea can cut 4 pieces that are 2 1/10 feet long from the fabric.
