This question says Vera's dinner plate is divided into three equal size sections. Vera puts all her broccoli in one section, and then we're asked what fraction of Vera's plate has broccoli.

Okay, so we have a plate with three equal size sections, and we know that Vera puts broccoli in one section. We're asked to figure out what fraction of the plate that is. So we can draw Vera's plate, trying to represent this with a picture. Maybe Vera's plate is a rectangle. We don't really know, but a rectangle will work as long as it has three equal size sections.

So let's try to draw that. This may not be perfect; we can probably do that second one a little better, but this should represent three equal size sections on a plate.

And then we know she puts broccoli in one of those sections, so let's use green to draw some broccoli. Broccoli, broccoli, broccoli.

Then, look at this picture and ask ourselves: What fraction of Vera's plate has broccoli? Well, our fraction is going to have a numerator on top, which will be how many sections have broccoli, which is one.

Then our denominator will be out of the total number of equal sections, and we know there are three equal size sections. So, 1 out of 3, or one of the three sections has broccoli.
