If a stock of food can feed 20 chickens for 24 days, how long would the same food of stock last if there were 16 chickens ?

A stock is equivalent to 20 x 24 chicken-days = 480 chicken-days.
What this means is that the same stock of 480 chicken-days can feed 1 chicken for 480 days, or feed 480 chickens for 1 day.
Since
480 chicken-days divide by 16 chicken = 30 days
Thus, the same stock can feed 16 chickens in 30 days.
Hope this helps.

x = 24 * 20 / 16

20 chickens for 24 days
1 chicken for 24x20 days
16 chickens for (24x20)/16 = 30 days
( the assumption is that the chickens consume equally)

20 chicken 24 days
thus
10 chicken 12 days
thus
1 chicken 1.2 days
tus 16 chickens 16 * 1.2 days

find out how long it can last one chicken. so it;s 20x 24 . then to find out if there is 16 chickens , take the previous answer and divide it by 16.
sure hope i got it right

in one day it can feed 480 chickens.
480/16=30
it can feed 16 chickens for 30 days .

s/c=d
s= original stock
c= no of chickens
d= days
s/20=24
s=480
480/16=30

stock of food : s = cte
number of chicken in first example: c1 = 20
time in1rst example: t1 = 24 days
number of chicken example 2: c2=16
time in example 2: t2=?
c1 * t1 = c2 * t2 = s = cte
t2 = c1 * t1/c2 = 30 days

hey dont fool me. i'm also a 14 year old. such questions dont suit 14 year olds.
u should ask questions like those in which i'm stuck like how to integrate sqrt [ (1+u^2) / (1-u^2) ]
