Are the bananas heavier or lighter than a kilogram?

In the picture, we can see a set of balancing scales. On one end, there’s a bunch of bananas. And at the other end, we have a metal weight. We can see that this is labeled one kg. And this shows us that the unit of measurement is a kilogram. This is a kilogram weight. So what these scales are helping us to do is to compare the masses of these two objects. And this is why the question asks us, are the bananas heavier or lighter than a kilogram?

What do you notice about the position of the scales? This end of the scales is further down, isn’t it? This shows that the kilogram weight is heavier than the bananas. So we can say that the bananas are lighter than the kilogram. We don’t know how heavy the bananas are exactly. But by looking at our set of balances, we can say that the bananas are lighter than a kilogram.
