Can you help on this? A farmer has 96 more chickens than ducks.After he sold 20 ducks,he had 3 times as many chickens than ducks.How many chickens did he have? Is there any different between ” 3 times as many chicken THAN duck” vs “3 times as many chicken as duck” ?

This is a Before After question.
As Primary 3, we shall use the modal method.
In the end, (you draw the modal as follow)
chicken 3u
duck 1u
Comparison = 3u – 1u = 2u
Comparison = 96 + 26 = 122 (as you sell 20 ducks, the chicken is 20 more than the ducks)
2u = 122
1u = 122 ÷ 2 = 61
3u = 3 x 61 = 183 chickens
a) 3 times as many chicken as duck means chicken 3u and duck 1u.
b) 3 times more chicken than duck means chicken 4u and duck 1u.
