Answer:
We are given that,
Length of the eraser = [tex]1\dfrac{1}{3}=\dfrac{4}{3}[/tex] inches.
Then, the length of the pen is 4 times the length of the eraser gives,
Length of the pen = [tex]4\times \dfrac{4}{3}=\dfrac{16}{3}[/tex] inches
So, we get that,
Length of eraser = [tex]\dfrac{4}{3}[/tex] inches.
Length of pen = [tex]\dfrac{16}{3}[/tex] inches.
