each piece will be 2 1/3 yards
Step-by-step explanation:
Total fabric Mary has = 7 1/4 yards
She cuts off = 3/4 ft
First we need to convert from foot to yard the part cut off. Then we subtract the part that was cut off from the total fabric.
Subtracting the part cut off:
We are informed Mary want 3 pieces of the fabric of same size after the fraction has been cut off.
we divide 7yards into 3:
Hence, each piece will be 2 1/3 yards
