If you write down your information first it will be easier to visualise a method:
15 rolls of ribbon, each is [tex]5\frac{3}{8}[/tex] yards long. 10 wedding baskets. She takes [tex]\frac{3}{4}[/tex] yards away from every basket.
So, in mathematical terms:
[tex](15*5\frac{3}{8})-10(\frac{3}{4})\\\\(15*\frac{43}{8})-5(\frac{3}{2})\\\\(\frac{645}{8})-\frac{15}{2}\\\\\frac{645}{8}-\frac{60}{8}\\\\\frac{585}{8}\\\\585/8=73.125[/tex]
Your answer is [tex]\frac{585}{8}[/tex] or 73.125 yards.
