since each block is 3/8 of a mile, then how many miles in 4½? well, it'd just be their product, but let's firstly convert the mixed fraction to improper.
[tex]\bf \stackrel{mixed}{4\frac{1}{2}}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}} \\\\\\ \cfrac{9}{2}\cdot \cfrac{3}{8}\implies \cfrac{27}{16}\implies 1\frac{11}{16}[/tex]
