Work Step by Step
Price of 6.5 ft long chain is dollar 24.64.
Price of chain of 1 ft = Total cost of chain of 6.5 ft $\div$ 6.5 ft
= 24.64 $\div$ 6.5
= $\frac{2464}{100}\div\frac{65}{10}$ (convert decimal to fractions)
= $\frac{2464}{100}\times\frac{10}{65}$ (division of fraction is multiplication with the reciprocal of second fraction )
= $\frac{1232}{5}\times\frac{1}{65}$
=$\frac{1232}{325}$
= 3.790
Now to round to the nearest cent we keep 3.79 and look the thousandths place it is $\leq$ 4. So the asnwer is 3.79
