Question

-4 1/2 • 6 3/4 write in proper fraction

Answer 1

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

`\stackrel{mixed}{4(1)/(2)}\implies \cfrac{4\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{9}{2}}~\hfill \stackrel{mixed}{6(3)/(4)} \implies \cfrac{6\cdot 4+3}{4} \implies \stackrel{improper}{\cfrac{27}{4}} \\\\[-0.35em] ~\dotfill\\\\ -\cfrac{9}{2}\cdot \cfrac{27}{4}\implies \cfrac{-9\cdot 27}{2\cdot 4}\implies -\cfrac{243}{8}\implies {\Large \begin{array}{llll} -30(3)/(8) \end{array}}`
