Answer: [tex]\frac{16}{21}[/tex]

Step-by-Step Explanation:

KCFmeans: Keep, Change, Flip

  • Keep: the first fraction
  • Change: the sign from division to multiplication
  • Flip: the second fraction

  [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{7}{8}[/tex]

= [tex]\frac{2}{3} * \frac{8}{7}[/tex]   KCF is applied here!

= [tex]\frac{2(8)}{3(7)}[/tex]

= [tex]\frac{16}{21}[/tex]
