Question

Multiply 39. 1/2 and 24. 3/4

Answer 1

let's firstly convert the mixed fractions to improper fractions.

`\stackrel{mixed}{39(1)/(2)}\implies \cfrac{39\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{79}{2}}~\hfill \stackrel{mixed}{24(3)/(4)} \implies \cfrac{24\cdot 4+3}{4} \implies \stackrel{improper}{\cfrac{99}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{79}{2}\cdot \cfrac{99}{4}\implies \cfrac{7821}{8}\implies {\Large \begin{array}{llll} 977(5)/(8) \end{array}}`
