Teachers, this looks easy but I am unable to do. Again I need to learn how to draw model, I draw 4 units mangoes and 7units of pears. The difference is 3 units. Then how do I go from here when 12 pears were taken out?

Ans is 49
9+12 =3u
U=7
U=7
7*7 is equal to 49
They said they remove 12 so u must work backwards
Since the diff is 9 after removing so u find the difference before removing which is 12+9
Thats how u get 3 units
item 【mango】unchanged → b4 vs aft
