#### Answer

13$\frac{5}{7}$ or 13 lengths

#### Work Step by Step

Length of the radiator hose = 6 ft roll = 6 x 12in = 72in
Length of one cut = 5$\frac{1}{4}$ in
Therefore number of radiator hose that can be cut = 72in $\div$ 5$\frac{1}{4}$ in
= 72in $\div$ $\frac{21}{4}$
= 72in $\times$ $\frac{4}{21}$
= $\frac{96}{7}$
=13$\frac{5}{7}$ or 13 lengths
