Question

Five carpenters working at the same rate can finish a school's furniture order in 8 days. What part of the order will one carpenter complete in 4 days?

Answer 1

Answer:
`(1)/(10)` of the order.

Explanation:

1. You have that number of carpenters decreases from 5 carpenters to 1 carpenter. Therefore, this decreases by the following factor:

`factor_(1)=(1)/(5)`

2. The number of days decreases from 8 days to 4 days. Then, the factor is:

`factor_(2)=(4)/(8)=(1)/(2)`

3. The order is a furniture, therefore, you can solve the problem as following, where
`x` is the part of the order completed by one carpenter in 4 days:

`x=(order)(factor_(1))(factor_(2))\\x=(1)((1)/(5))((1)/(2))\\x=(1)/(10)`
