This math topic focuses on understanding equivalent fractions using visual representations with images of pizzas. Learners are asked to determine how many slices a pizza would be cut into so the fraction represented by the shaded slices remains equivalent across different images. Each question presents an image of a pizza, sliced in a specific way with certain slices shaded, and students must choose from multiple potential denominators that would keep the fraction equivalent when the pizza is re-sliced. This exercise belongs to an introductory unit on equivalent fractions.
