Answer 1

$4\frac{3}{16}+5\frac{1}{16}=(4+5)+(\frac{3}{16}+\frac{1}{16})=9+\frac{3+1}{16}=9+\frac{4}{16}=9+\frac{4:4}{16:4}\\\\=9+\frac{1}{4}=\boxed{9\frac{1}{4}=9\frac{1\cdot25}{4\cdot25}=9\frac{25}{100}=9.25}\leftarrow total\ ribbon\\\\Answer:\boxed{9.25\cdot\ 1.60=\ 14.80}$

Answer 2

4 3/16=(4·16+3)/16=67/16=4,1875 (pink ribbon)
5 1/16=(5·16+1)/16=81/16=5,0625 (green ribbon)
4,1875+5,0625=9,25 (total)
9,25·1,60=$14,8

Answer: $14,8
