What is 3 3/4 * 3 * 3 1/4 equal out to be? need help please!!​

Answer 1

let's firstly convert the mixed fractions to improper fractions and then multiply.

`\bf \stackrel{mixed}{3(3)/(4)}\implies \cfrac{3\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{15}{4}}~\hfill \stackrel{mixed}{3(1)/(4)}\implies \cfrac{3\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{13}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{15}{4}\cdot 3\cdot \cfrac{13}{4}\implies \cfrac{15}{4}\cdot \cfrac{3}{1}\cdot \cfrac{13}{4}\implies \cfrac{595}{16}\implies 36(9)/(16)`
