About this video
Vera's plate has three equal-sized sections and broccoli is in one of them. The video draws the plate and shows that the fraction with broccoli is 1/3: the numerator counts sections with broccoli and the denominator counts all the equal sections.
You'll be able to
- draw a picture to solve a fraction word problem.
- write a unit fraction using the numerator and denominator correctly.
Key words
- numerator
- The top number; here, how many sections have broccoli.
- denominator
- The bottom number; the total number of equal sections.
- section
- One part of something that has been divided up.
Transcript
- [Voiceover] This question says, Vera's dinner plate is divided into three equal-sized 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 we plate with three equal-sized sections, and we know that Vera puts broccoli in one section, and we're asked to figure out what fraction of the plate that is.
So we can draw Vera's plate, try 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-sized 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-sized sections on a plate.
And then we know she puts broccoli in one of those sections, so let's use green, draw some broccoli. Broccoli, broccoli, broccoli. And then, look at this picture, and ask ourselves, what fraction of Vera's plate has broccoli? Well, our fraction's gonna have a numerator.
On top will be how many sections have broccoli, which is one, and then, our denominator will be out of the total number of equal sections, and we know there are three equal-sized sections. So 1/3 or one of the three sections has broccoli.
