Five chickens eat 10 bags of scratch in 20 days. How long does it take 18 chickens to eat 100 bags of scratch?

5 chickens eats 10 bags in 20 days

1 chicken eats 2 bags in 20 days

18 chickens eat 36 bags in 20 days

100 bags/36 bags=2 7/9 times as many bags so it will take 2 7/9 times as many days

(2 7/9)*20=(25/9)*(20)=500/9=55 5/9 days

(10 b /20 d ) / 5c    = 1/10  b / cd

 

 1/10   b / (cd)   *  18 c  = 1.8 b/d

 

100 b / (1.8 b/d) = 55.56 d
