Answer:
[tex]\dfrac{1}{2}[/tex] day
Step-by-step explanation:
Given that:
Owen who is an alien has only 4/5 of his socks clean.
and he wears 2/5 socks a day.
Out of his total 4/5 clean socks.
It will take him (4/5 ÷ 2/5) days to wash all his socks
i.e
the numbers of days since he washed all his socked is:
= [tex]\dfrac{4}{5} \div \dfrac{2}{5}[/tex]
= [tex]\dfrac{4}{5} \times \dfrac{5}{2}[/tex]
= [tex]\dfrac{1}{2}[/tex]
