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