16 men in 12 days can do 0.5work
1 man 1 day can do 0.5/(16x12) of a work
8days to do 0.5 of a work
1 man 8 days can do 8x0.5/(16x12) = 0.5x(1/24) of a work
... if you notice we need 24 men
... more detail
in8days, 0.5x(1/24) of a work need 1 man
in8days, 0.5 of a work need 0.5/(0.5x(1/24)) = 24 men
point is to find 'amount of work done per man per unit of time' then work out from that.
tis noteworthy that the slope is negative, meaning the line is dropping down from left-to-right, so is lower on the right-side, namely it has a negative "rise".

![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Step-by-step explanation:
A pair of factors are two factors of a number, when multiplied, gives the number.
![3* 12=36](https://tex.z-dn.net/?f=3%2A%2012%3D36)
![4*9=36](https://tex.z-dn.net/?f=4%2A9%3D36)
The pairs 3, 12 and 4, 9 are factor pairs of 36.
