Question

-1 2/3 multiply by -7 1/2

Answer 1

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

`\stackrel{mixed}{1(2)/(3)}\implies \cfrac{1\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{5}{3}}~\hfill \stackrel{mixed}{7(1)/(2)} \implies \cfrac{7\cdot 2+1}{2} \implies \stackrel{improper}{\cfrac{15}{2}} \\\\[-0.35em] ~\dotfill\\\\ \left( -\cfrac{5}{3} \right)*\left(-\cfrac{15}{2} \right)\implies \cfrac{5}{3}* \cfrac{15}{2}\implies \cfrac{5}{2}* \cfrac{15}{3}\implies \cfrac{5}{2}* 5\implies \cfrac{25}{2}\implies 12(1)/(2)`
