Decomposing Fractions and Improper Fractions

The video tutorial explains the concept of decomposing numbers and fractions. It starts with a brief introduction to decomposing whole numbers and then focuses on fractions, using tape diagrams to visually represent the process. The tutorial covers unit fractions and demonstrates how to decompose fractions like 3/8 into smaller parts. It also addresses improper fractions, showing how to decompose them by extracting whole numbers. The video encourages practicing these skills to prepare for working with mixed numbers and performing operations with fractions.

What does it mean to decompose a number?
