Density Property Many of my students are afraid of fractions, but they are very useful in algebra and upper levels of math. They can actually make the problem easier to solve and they frequently make more sense than decimals.

In algebra, teachers can tell if you are using a calcultor for solving all your problems because you give your answer in decimals instead of fractions. If you absolutely cannot do fractions then I strongly suggest you get a calculator that can do fractions for you. In common usage, a fraction is a part of a unit.

In mathematics, a fraction is a quotient divide problem or a ratio. In common usage and lower levels of math, improper fractions must be changed to a mixed number. But in algebra and high levels of math, an improper fraction can have more meaning and can actually be the preferred answer.

Fraction Definitions Most schools teach students about common fractions. The numerator, the top part of the fraction, represents a number of equal parts. The denominator, the bottom part of the fraction, tells how many of those parts make up a whole.

A proper fraction is a fraction where the numerator is smaller than the denominator. An improper fraction is one where the numerator is larger. The can be converted into a mixed numer consisting of a whole numer part and a fraction part.

The reciprocal or multiplicative inverse of a fraction is the the fraction that can be multiplied by the original with the answer equal to one 1. Commutative Property for Fraction Addition The order in which two fractions are added does not affect the sum answer.

Associative Property for Fraction Addition The sum of three fractions is the same no matter how you group the fractions. Additive Property of Equality If you add equal amounts to both sides of an equation, the equation is still equal. Commutative Property for Fraction Multiplication The order in which two fractions are multiplied does not affect the product answer.

Associative Property for Fraction Multiplication The product of three fractions is the same no matter how you group the fractions. Multiplicative Identity Property for Fraction Multiplication One multiplied by any number is the number itself.

Multiplicative Property of Equality If you multiply equal amounts by everything on both sides of an equation, the equation is still equal.

Density Property of Fractions.(associative property) Note, for example, that if A is nxm, B is mxk, and C is kxl, then the above products are possible (in this case, (AB)C is nxl matrix). 2. The commutative property is one of several properties in math that allow us to evaluate expressions or compute mental math in a quicker, easier way.

This is a well known number property that is . Multiplication allows you to do repeated addition quickly and efficiently. You can write a multiplication sentence to show groups of 3 pennies. The numbers you multiply are called factors. The answer is The Associative Property shows that changing the grouping of the factors does not change the product.

(4 x 2) x 1 = 4 x (2 x 1) 8 x 1. equation, value, commutative property for addition, commutative property for multiplication, associative property for addition, associative property for multiplication Student/Teacher Actions (what students and teachers should be doing to facilitate learning).

In addition, division, compositions of functions and matrix multiplication are two well known examples that are not commutative..

Division (Not Commutative) Division is probably an example that you know, intuitively, is not commutative. commutative property for multiplication as the term for this “order property.” 3. Put students into pairs, and give each pair a copy of the Example/Non-Example Mat and a.
