Answer:
[tex]33\frac{3}{8}[/tex]
Step-by-step explanation:
A piece of crown molding is 64 1/4 inches long
[tex]64 \frac{1}{4} =\frac{64 \cdot 4+1}{4} =\frac{257}{4}[/tex]
you cut 30 7/8 inches off
[tex]30 \frac{7}{8} =\frac{30 \cdot 8+7}{8} =\frac{247}{8}[/tex]
[tex] \frac{247}{8}[/tex] is cut off. So we subtract from the length of crown
[tex]\frac{257}{4}-\frac{247}{8}[/tex]
Make the denominators same . LCD is 8
[tex]\frac{514}{8}-\frac{247}{8}[/tex]
[tex]\frac{267}{8}[/tex]
[tex]33\frac{3}{8}[/tex]
