What fraction of the biscuits have been eaten?

 

Hello Guest!

 

\(\frac{\frac{1}{6}packet+\frac{1}{2}packet}{1\frac{1}{3}packets}=\frac{x}{100\%}\\ \frac{\frac{1+3}{6}}{\frac{4}{3}}=\frac{x}{100\%}\)

\(\frac{4}{6}:\frac{4}{3}=x:100\%\\ x=\frac{100\%\times 4\times 3}{6\times 4}\)

\(x=50\%\)

 

Karly and her friend ate 50% of biscuits,

these are 2/3 packages biscuits.
