In the video, a woman is standing in front of a whiteboard and writing on it with a marker. She is wearing a grey sweater and has her hair tied back. The whiteboard has a diagram of a pizza with slices and a fraction written on it. The woman is explaining the concept of a fraction, specifically 1/9, and how it relates to a whole pizza. She is using the marker to point out different parts of the diagram and the fraction on the board. The video is shot in a classroom setting, and the woman appears to be a teacher or instructor.
