  Fraction (mathematics) Summary
Subtraction of fractions is similar to addition, in that the fractions being subtracted must have a common denominator.
In mathematics, a fraction is a way of expressing a quantity based on an amount that is divided into a number of equal-sized parts.
Multiplying the numerator and denominator of a fraction by the same (non-zero) number results in a new fraction that is said to be equivalent to the original fraction.

 fraction (mathematics)
as a fraction and 37% as a percentage.
Fractions are also known as rational numbers;; that is, numbers formed by a ratio.
To add or subtract with fractions a common denominator (a number divisible by both the bottom numbers) needs to be identified.

The study of fractions is foundational in mathematics, yet it is among the most difficult topics of mathematics for school students.
In the fourth module, fraction strips are used to help students develop an understanding of what is meant by partitioning a whole length into equal fractional lengths, of estimating fractional lengths, and of measuring distances.
Fraction equivalence and ordering are then introduced using area models before students are asked to develop the same concepts using a discrete model such as counters.

 Fraction (mathematics) - Wikipedia, the free encyclopedia
The numerator and denominator are the "terms" of the fraction.
A vulgar fraction (or common fraction) is a rational number written as one integer (the numerator) divided by a non-zero integer (the denominator), for example
A complex fraction (or compound fraction) is a fraction in which either the numerator or denominator or both contain a fraction.

Mathematics, Science, and Technology Learning Standard 3 (Mathematics): Students will understand mathematics and become mathematically confident by communicating and reasoning mathematically, by applying mathematics in real-world settings, and by solving problems through the integrated study of number systems, geometry, algebra, data analysis, probability, and trigonometry.
Students will be able to use fraction bars to visualize addition of fractions by lying one fraction bar on top of another and locate a third fraction bar that is equal to these first two.
Additionally, students will also be given "higher order thinking" to stimulate their previous knowledge and apply fractions to things which are not always thought of as fractional, even though we have covered it in the opening lesson.

 Egyptian Fraction -- from Wolfram MathWorld
An Egyptian fraction is a sum of positive (usually) distinct unit fractions.
The reason the Egyptians chose this method for representing fractions is not clear, although André Weil characterized the decision as "a wrong turn" (Hoffman 1998, pp.
Any fraction with odd denominator can be represented as a finite sum of unit fractions, each having an odd denominator (Starke 1952, Breusch 1954).
