Exploring Operations with Fractions and Decimals

This video tutorial covers performing all four basic operations—addition, subtraction, multiplication, and division—on rational numbers, including fractions and decimals. It begins with an introduction to the topic, followed by warm-up problems to practice subtraction and division. The video then provides a refresher on fraction operations and compares different operations through side-by-side examples. A complex problem involving mixed operations is solved, and the session concludes with a word problem example. The tutorial emphasizes the importance of common denominators and the use of strategies like 'keep change flip' for division.
