If she has 3/12 yards and 2/4 yards on another piece of fabric, the total quantity of fabric is the sum of both of them:
[tex]\frac{3}{12}\text{ + }\frac{2}{4}\text{ = }\frac{3\text{ + 6}}{12}\text{ = }\frac{9}{12}[/tex]It means that she already has enough fabric to make a quilt, because she has more than 8/12 yards
