Ordering Rational Numbers
Practice ordering rational numbers in Grade 9 math — To order from least to greatest, read the numbers on the number line from left to right. Part of Real Numbers and Basic Operations for Grade 9.
Key Concepts
Property Use a number line to order the numbers. To order from least to greatest, read the numbers on the number line from left to right. Converting fractions to decimals can make it easier to see their positions.
Examples Order from least to greatest: $\frac{3}{4}, 1, 0.85, \frac{5}{8}$. First, convert values to decimals for easy comparison: $0.75, 1, 0.85, 0.625$. Reading from left to right on the number line, the final order is: $ 1, \frac{5}{8}, \frac{3}{4}, 0.85$.
Explanation Imagine numbers are runners in a race, and the number line is their track! To find the order, just see who's behind (left) and who's ahead (right). Turning messy fractions into clean decimals helps you see exactly where each runner is placed.
