Question

A piece of crown molding is 64 1/4 inches long.If you cut 30 7/8 inches off,how much crown molding is left

Answer 1

33 and 3/8ths is the answer 

Answer 2

`33(3)/(8)`

Explanation:

A piece of crown molding is 64 1/4 inches long

`64 (1)/(4) =(64 \cdot 4+1)/(4) =(257)/(4)`

you cut 30 7/8 inches off

`30 (7)/(8) =(30 \cdot 8+7)/(8) =(247)/(8)`

`(247)/(8)` is cut off. So we subtract from the length of crown

`(257)/(4)-(247)/(8)`

Make the denominators same . LCD is 8

`(514)/(8)-(247)/(8)`

`(267)/(8)`

`33(3)/(8)`
