Answer: [tex]\frac{1}{10}[/tex] of the order.
Step-by-step explanation:
1. You have that number of carpenters decreases from 5 carpenters to 1 carpenter. Therefore, this decreases by the following factor:
[tex]factor_{1}=\frac{1}{5}[/tex]
2. The number of days decreases from 8 days to 4 days. Then, the factor is:
[tex]factor_{2}=\frac{4}{8}=\frac{1}{2}[/tex]
3. The order is a furniture, therefore, you can solve the problem as following, where [tex]x[/tex] is the part of the order completed by one carpenter in 4 days:
[tex]x=(order)(factor_{1})(factor_{2})\\x=(1)(\frac{1}{5})(\frac{1}{2})\\x=\frac{1}{10}[/tex]
