Answer:
[tex]\frac{3}{4} Yards[/tex]
Step-by-step explanation:
Andi needs [tex]5\frac{1}{2}[/tex] yards of fabric for a project.
[tex]\text{At School, she has: } 3\frac{1}{4} yards\\\text{At Home, she has: } 1\frac{1}{2} yards\\\text{Length of Fabric already owned by Andi= } 3\frac{1}{4} +1\frac{1}{2}\\=4+\frac{1}{4}+\frac{1}{2}\\=4\frac{3}{4}\\\text{Therefore, the Length of Fabric needed by Andi= } 5\frac{1}{2}-4\frac{3}{4}\\=\frac{3}{4} Yards[/tex]
Andi needs [tex]\frac{3}{4} Yards[/tex] more of Fabric.
