| Fractions |
Fractions can be thought of as another room of seeing division. If you have one whole pizza and two people want to share it equally, they will divide it into two halves :
The penetrate numeral of a divide is the denominator. It tells how many parts a wholly has been divided into. In this sheath our pizza is divided into two parts .

| Proper Fractions, Improper Fractions, and Mixed Numbers |
A proper fraction is one in which the numerator is smaller than the denominator .
An improper fraction is one in which the numerator is larger than the denominator. If the numerator is larger than the denominator, the divide equals a number that is greater than one .

| Finding the GCF (Greatest Common Factor) |
The greatest coarse factor is the largest factor that divides two numbers. We find this by figuring out what prime numbers are multiplied in concert to make up each number. A prime count is a number that can entirely be divided by itself or by one. Examples of premier numbers are 1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, etc. We want to focus on those that are less than ten in most cases .

| Adding and Subtracting Fractions |
To add or subtract two fractions, the two fractions must have the lapp denominator. consequently, you will have to find the lowest park denominator and change each divide to an equivalent fraction. then you add or subtract the numerators as indicate and put the resultant count over the denominator and reduce the fraction to lowest terms .
| Multiplying and Dividing Fractions |
Multiplying fractions is fairly simpleton. You may want to put each fraction in its lowest terms to start. then multiply the numerators to get a numerator and multiply the denominators to get a new denominator. And reduce or simplify the fraction to put it in its lowest terms. If you are multiplying a fraction by an integer, put the integer over one to make a divide of it .
Examples :
Five times 4/5 : Put the five over one, then multiply 5 x 4 to get 20 and 1 x 5 to get 5. Twenty can be divided evenly by 5 to give us an answer of 4.
| Reciprocals of Fractions |
The intersection of a number and its multiplicative inverse equals 1 .
| Signs and Fractions |
If either the denominator or numerator is negative, the fraction is considered a negative fraction. If both the denominator and the numerator are veto, the fraction is considered to be a positive divide .
Adding two fractions of the like augury ( either positive or damaging ) gives an answer with the same sign. You may need to give the fractions common denominators first .
