Number Balance

Stage: 1 Challenge Level: Challenge Level:2 Challenge Level:2

Amy from Stoke by Nayland Middle School sent us her work on this problem.

On the first question you would need to put a weight on number $2$ on the right side.

On the second question you would need to put a weight on number $7$ on the left side.

On the third question you could put one weight on 1 on the left side and the other on $2$ on the right side.

Good work, Amy!

Sam from Shepherd School noticed that there were several answers for the third question.

You could put them on point $6$ on the right and point $5$ on the left, for example. There are $9$ solutions to this, they could go anywhere where the weight on the right is 1 more than the weight on the left.

Well done Sam!
