Lesson 4 Converting Between Improper Fractions and Mixed Numbers 
You are getting ready to do some basic arithmetic operationsaddition, subtraction, multiplication, and divisionwith fractions and mixed numbers. These operations often require you to convert between improper fractions and mixed numbers. To begin, here is a review of the basic definition.
Definitions A proper fraction is one where the numerator is smaller than the denominator.
An improper fraction is one where the numerator is greater than, or equal to, the denominator.
A mixed fraction is one that includes an integer as well as a fractional part.

Topic 1
Converting Improper Fractions to Mixed Numbers
Arithmetic operations with fractions often result in fractions in an improper form. You should finish the work be converting this answer to a proper proper fractions (and reducing if possible).
Suppose an addition operation results in an improper fraction such as ^{11}/_{3}. Converting to a mixed number, the answer becomes 3^{ 2}/_{3}. This section describes how to make this important kind of conversion.
Procedure Converting improper fractions to mixed numbers Step 1: Divide the denominator into the numerator.
Step 2: Assemble the mixed number.
Note: If there is no remainder in Step 1, then the mixednumber part is a whole number. There is no fraction part. 
Example:
^{10}/_{5} = 2
Steps for converting an improper fraction
to a proper mixed number.
Sometimes the fractional part of these conversions needs to be reduced.
Example: Convert ^{12}/_{8} to a mixed number.
 Doing the division: ^{12}/_{8} = 1 R 4
 Assembling the mixed number: ^{12}/_{8} = 1 ^{4}/_{8}
 Reducing the fraction: 1 ^{4}/_{8} = 1 ^{1}/_{2}

Topic 2
Converting Mixed Numbers to Improper Fractions
Converting mixed numbers to improper fractions is often necessary for setting up arithmetic operations with fractions.
Procedure Converting mixed numbers to improper fractions.
Note: A whole number can be expressed as an improper fraction by putting that number over 1. 
Example:
14 = ^{14}/_{1}
