well, how much is 4/5 of 3 and 1/4? well, is just their product, thus, firstly, let's change the mixed fraction to "improper" and proceed,


\bf \stackrel{mixed}{3(1)/(4)}\implies \cfrac{3\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{13}{4}}\\\\ -------------------------------\\\\ \cfrac{4}{5}\cdot \cfrac{13}{4}\implies \cfrac{13}{5}\implies 2(3)/(5)
