$\boxed{Refer \: to \: the \: attachment}$

Answer 2

$Time \: taken \: by \: Ella \: to \: complete \: painting = \frac{13}{5} hrs.$

$Time \: taken \: by \: Holly \: in \: comparison \: to \: Ella = \frac{3}{4} \: of \: \frac{13}{5} hrs$

$\implies \frac{39}{20} hrs = 1 \frac{19}{20} \: hrs$

So time taken to complete 5 paintings

$time \: taken \: in \: 1 \: painting \: \times 5$

$\frac{39}{20} \times 5$

$\frac{39}{4} \: hrs$

$9.75 \: hrs$
