If one worker can finish a piece of work in 10 days, how many workers, each working at the same rate as the first, will be needed to finish the work in 50 days?

Ratio:
1 person:10 days
0.2 persons:50 days

You will need 0.2 workers.. (kind of weird) to finish the work in 50 days

Hope this helps =)

This is an indirect proportion. This is how I solve it:

First, we need to know the rate of one worker, and this is equal to [tex] \frac{1}{10} [/tex]. This means he completes 1/10 of the work in a day.

So since Distance= Rate * Time (Think of distance as the reciprocal of the number of workers), we would have:

[tex] \frac{x}{ \frac{1}{10} } =50 \\ x=5[/tex]

So we take the reciprocal which is 1/5 or 0.2 so we have 0.2 workers. (Are you sure that the given is ;ike this?)
