c:d=6:5 63 ducks sold then the ratio is not 3:1 so 3:1 times 2:2=6:2 so from 6:5 then 63 weere sold becomes 6:2 therefor 3 duck units=63 therefor 3/63=1/21 1 unit=21 there is not question so I will solve for 1. total number 2. original numbe rof chickens 3. original number of ducks 4. final numbe rofo ducks
total number=total units times number per unit number per unit=21 ttoal units=5+6=11 21 times 11=231
total=231
chickens=6 units 6 times 11=126
original ducks=5 units 5 times 21=105
resulting number of ducks 2 units 2 times 21=42
total=231 original chickens=126 original ducks=105 final number of ducks=42
