2/8 = 5/y...2 roosters to 8 chickens = 5 roosters to y chickens
cross multiply because this is a proportion
(2)(y) = (8)(5)
2y = 40
y = 40/2
y = 20....so with 5 roosters comes 20 chickens
2/8 reduces to 1/4....so with 1 rooster comes 4 chickens
ur table :
roosters : 2.....1......5
chickens: 8.... 4.....20
