Understanding Fractions and Their Applications
This comprehensive page covers several key aspects of fractions and their practical applications. The content begins with fundamental concepts and progresses through various representations and operations.
Definition: A fraction is used to represent parts of a whole, written as a/b where a and b are whole numbers, with a being the numerator and b being the denominator.
Example: Visual representations show fractions through colored portions, such as 2/3 of a disk or 3/4 of a rectangle.
Highlight: When working with fraction partage 6ème, understanding the relationship between the numerator and denominator is crucial:
- If numerator < denominator: fraction is less than 1
- If numerator > denominator: fraction is greater than 1
- If numerator = denominator: fraction equals 1
Vocabulary: Key terms include:
- Numerator: the number above the fraction line
- Denominator: the number below the fraction line
- Quotient: the result of dividing the numerator by the denominator
Example: For placer une fraction sur une droite graduée cm2, practical examples include:
- 1/2 = 0.5
- 3/4 = 0.75
- 6/5 = 1.2
Highlight: For comparing fractions:
- With same denominators: compare numerators (13/20 < 27/20)
- With same numerators: compare denominators (larger denominator means smaller fraction)
The page concludes with important notes on fraction equivalence, achieved by multiplying or dividing both numerator and denominator by the same number.
