Understanding Fractions and Decimals

This video tutorial covers the process of comparing and ordering rational numbers by converting them into equivalent decimals or fractions. It explains how to use number lines for ordering and emphasizes the importance of place values. The tutorial also demonstrates simplifying fractions and ordering mixed numbers and decimals. The lesson concludes with a brief introduction to the next module on applying GCF and LCM to fraction operations.

What is the first step in comparing and ordering rational numbers?

• Subtract the smallest number from the largest

• Add all numbers together

• Write all numbers in the same form, either as decimals or fractions

• Convert all numbers to percentages
