Answer:

John would have 0.79 feet of wire left over after fixing the lamp

Step-by-step explanation:

Given:

Length of the wire John needed for fixing the lamp = 13.71 feet

Length of wire John bought from the hardware store = [tex]14\frac{1}{2}[/tex]

To Find:

Length of wire left with John after fixing the lamp = ?

Solution:

Lets first convert the mixed fraction into decimal form

[tex]14\frac{1}{2}[/tex]

=> [tex]\frac{2 \times 14 +1}{2}[/tex]

=>[tex]\frac{29}{2}[/tex]

=> 14.5

So John Bought 14.5 feet of wire

Now

let the wire that is left with John after Fixing the lamp be X

Then,

X = length of wire john bought - Length of wire needed for fixing the lamp

X=  14.5  -   13.71

X = 0.79
