Total weight of the sold fruits = [tex]\frac{8}{10}[/tex]
Weight of blueberries is [tex]\frac{3}{4}[/tex] of total weight of [tex]\frac{8}{10}[/tex]
So, weight of blueberries is = [tex]\frac{3}{4}\times\frac{8}{10}=\frac{3}{5}[/tex]
Hence, weight of blueberries is [tex]\frac{3}{5}[/tex] pounds
Weight of raspberries = [tex]\frac{8}{10}-\frac{3}{5}[/tex]
=[tex]\frac{8-6}{10}[/tex] = [tex]\frac{2}{10}=\frac{1}{5}[/tex] pounds
