Comparing fractions with benchmarks
Compare fractions using benchmarks or common units
Problem types
- Compare fractions
- Compare unlike fractions
- Choose the fraction that fits the comparison
- Compare fractions with symbols
- Order three fractions into places
- Compare two fractions and say why
Builds on
- Generating equivalent fractions
- Comparing fractions · Earlier idea
Comparing fractions with the same denominator or numerator extends to unlike fractions by renaming them as equivalent fractions.
Leads to
- Adding and subtracting unlike fractions · See it applied
Deciding which of two fractions is greater with a common denominator is the same rewriting that adds and subtracts unlike fractions, and it lets a sum or difference be estimated from the nearest of 0, one half and 1.
- Comparing functions · See it applied
Comparing rates of change of two functions compares the fractions that give their slopes.
