Answer 1

If you write down your information first it will be easier to visualise a method:

15 rolls of ribbon, each is $5\frac{3}{8}$ yards long. 10 wedding baskets. She takes $\frac{3}{4}$ yards away from every basket.

So, in mathematical terms:

$(15*5\frac{3}{8})-10(\frac{3}{4})\\\\(15*\frac{43}{8})-5(\frac{3}{2})\\\\(\frac{645}{8})-\frac{15}{2}\\\\\frac{645}{8}-\frac{60}{8}\\\\\frac{585}{8}\\\\585/8=73.125$

Your answer is $\frac{585}{8}$ or 73.125 yards.
