Given
Ant takes 6 days to consume [tex]\dfrac{3}{8}[/tex] of an apple
Using unitary method
[tex]6\ \text{days}\rightarrow \quad \frac{3}{8}\ \text{of an apple}\\\\1\ \text{apple takes}\rightarrow \quad \frac{8}{3}\times 6=16\ \text{days}\\\\3\ \text{apples take}\rightarrow\quad 16\times3=48\ \text{days}[/tex]
