- Convert fractions and negative numbers to decimals to compare them accurately.
- Order a mixed list of rational numbers by comparing place value from left to right.
- Read and write an inequality chain that states a full ordering in one line.
What the lesson concludes
- Convert every value in a mixed list, fractions included, to decimal form before comparing.
- Compare digits from the highest place value down, moving right only when digits tie.
- A negative number further from zero is the smaller value, not the larger one.
- Finding a common denominator lets you compare fraction numerators directly.
- Read an inequality chain such as a less than b less than c as stating the full order in one line.
