How many yards of material from a 24-yard length of cloth remain after 3 pieces, each 3 1/2 yards long, and 5 pieces, each 2 1/4 yards long are removed.
----------------
24-[3*(3 1/2) + 5*(2 1/4)]
= 24 -[3*(7/2) + 5*(9/4)]
= 24 -[(21/2) + (45/4)]
= 24 -[(42/4)+(45/4)]
= 24 -[87/4]
= (96/4)-(87/4)
= 9/4
= 2 1/4 yrds.

from a length
pieces , each long,
pieces, each long are ; therefore, you need to subtract the sum of removed pieces from a length
and yards of material will
