Find the total dough required for one pie. $\frac{1}{4}+\frac{1}{8}=\frac{1\times2}{4\times2}+\frac{1}{8}=\frac{2}{8}+\frac{1}{8}=\frac{3}{8}$ Divide to find the number of pies that can be made. To divide by a fraction, invert and multiply. $12\ lb \div \frac{3}{8}\frac{lb}{pie}=12\ lb \times \frac{8}{3}\frac{pie}{lb}=\frac{96}{3}\ pies=32\ pies$
