Which Weighs More?

•
A balance scale is used to weigh different stones. The pictures on the scale
show the shapes of the stones.
The stones are NOT drawn to scale, so you cannot tell just by looking which
weighs more or less.
On the same scale, all stones of the same shape have the same weight.
However, each problem is separate from the others. Therefore, no one
problem gives an informtion about another problem.
Which stone weighs more? Write an inequality for each pair of stones. Explain how
you know.
