Question

A wooden flooring strip is 20 1/2 inches long. If you cut off 4 3/4 inches from one end what will be the new length of the strip in inches?

Answer 1

Length of wooden flooring strip = $20\frac{1}{2}$ or $\frac{41}{2}$

Length of strip cut off = $4\frac{3}{4}$ or $\frac{19}{4}$

So, the new length of the strip will be=

$\frac{41}{2}- \frac{19}{4}$

=$\frac{82-19}{4}=\frac{63}{4}$

Hence, the new length of the flooring strip will be $\frac{63}{4}$ inches and in mixed fraction it will be $15\frac{3}{4}$ inches.
