Gave away half of the remainder, which is half of your 1u, so the answer is 40.
Your model where you labelled the "give to nb" is incorrect, you should cut it into half...

Ans is 1)40
I got 40.
1) 4/5 x 400 = 320
2) 400 - 320 = 80
3) 1/2 x 80 = 40
1) 4/5 x 400 = 320
2) 400 - 320 = 80
3) 1/2 x 80 = 40

She had 400 cupcakes, she sold 4 over 5. Means 5 over 5 = 400 cupcakes
So you draw 5 bars = 400 cupcakes
Shade away 4 bars cause she sold it away.
5 units = 400 cupcakes
1 unit = 400 ÷ 5 = 80 cupcakes
Find 4 units ( the number that she sold away )
4 units = 80 x 4 = 320 cupcakes
Now she left 1 over 4. But half of the ones she left, she gave them away to her neighbours. So know you know she left 1 unit cause 5 units - 4 units she sold away = 1 unit. The 1 unit is 80 cupcakes. She gave them half way. So 80 x 1 over 2 = 40 OR
80 ÷ 2 = 40.
I hope it helps! :)
