Gabriela makes quilts to sell at charities. She can make 9 quilts with 36 yards of material. How many yards of material would she require for 13 quilts?
[tex]\text{Find how many yards she needs for 13 quilts}\\\\\text{We know that for 9 quilts, she used 36 yards}\\\\\text{To make this easier, find how many yards she needs for 1 quilt:}\\\\36\div9=4\\\\\text{She uses 4 yards per quilt}\\\\\text{Since we know this, multiply 13 by 4}\\\\13\cdot4=52\\\\\boxed{\text{52 yards}}[/tex]
