Answer 1

Dear Student,
1 packet of biscuit requires $2\frac{1}{2}$ cups of flour and $1\frac{2}{3}$ cups of sugar.
10 packets of biscuit require $2\frac{1}{2}\times 10$ cups flour and $1\frac{2}{3}\times 10cupssugar$
i.e. $$\begin{gathered} \frac{5}{2}\times 10=25cupflour \\ \frac{{\displaystyle 5}}{{\displaystyle 3}}\times 10=16.66\approx 17cup\left(approx\right)sugar. \end{gathered}$$

Regards.
