Lizzy: Clara brings a package of 100 stickers to school. She gives 10 stickers to a boy she likes. She gives half of the stickers which she has left to her best friends. How many stickers does Clara have left?.
Me: Hmmm, let me think. I think this is the detailed solution:
She gives the boy she likes 10 stickers. After giving the boy his stickers, she has 100 10 = 90 stickers left. She gives her best friends 90 / 2 = 45 stickers. This leaves Clara with 90 45 stickers = 45 stickers. Final answer: 45.
