Find highest common factor to simplify fractions. Express fractions in their simplest form. Recognize when fractions cannot be simplified further.
Simplifying fractions means expressing them in their lowest terms by finding the highest common factor of numerator and denominator and dividing both by it.
Express survey results and data in their simplest form for clearer communication and comparison.
Simplified fractions are easier to work with in calculations and help identify equivalent values quickly.
From reducing gear ratios to expressing proportions, simplified fractions appear throughout science and engineering.

What students often do wrong:
Students stop at the first common factor they find instead of finding the highest common factor, or think fractions like 5/10 cannot be simplified further.
Correct approach: Always find ALL common factors, then use the highest one. List factors systematically and double-check your work.
Memory tip: Keep simplifying until the only common factor left is 1. If you can divide both numbers by 2, 3, 5, etc., keep going!
Use the "factor ladder" method: keep dividing by small primes (2, 3, 5...) until you can't divide anymore. This ensures you find the highest common factor.
