fraction properties - i
summary
the content provides an in-depth exploration of basic fraction properties, crucial for solving gre math problems, including writing integers as fractions, handling fractions involving zero, understanding fractions of the form n/n, and the concept of reciprocals.
- fractions with a denominator of 1 simplify to the integer itself, enabling any integer to be written as a fraction, which is useful in various problem-solving scenarios.
- it is mathematically illegal to have a fraction with zero in the denominator, but zero can be in the numerator, where it always equals zero.
- for fractions of the form n/n, as long as n is not zero, the fraction equals 1, a principle that is fundamental when finding common denominators.
- the reciprocal of a fraction is its flipped version, and the product of a fraction and its reciprocal always equals 1, a key concept in solving problems involving fractions.
- understanding the relationship between a number and its reciprocal, especially in terms of their sizes, is essential for grasping the fundamentals of number sense.
