# Homeschool Fraction Guide

**Kinds of Fractions**

**Proper Fraction** – The Numerator is smaller than the Denominator. . 1/2 3/4 20/35

Ex

**Improper Fraction** – The Numerator is larger or equal to the Denominator. . 3/3 8/3 25/14

Ex

**Unit Fraction** – The Numerator is one. 1/2 1/5 1/8

Ex.

**Fractions Equal to Zero** – The Numerator is zero. 0/10 0/12 0/2

Ex.

**– The Numerator is exactly Divisible by the Denominator.**

Fractions Equal to Whole Numbers

Fractions Equal to Whole Numbers

*4/2 = 2*

**Ex.**100/25 = 4

36/4 = 9

**Ordering Fractions** – You make common Denominators and Equal Fractions. Then you order them with Common Denominators and then write the Fractions in their original form.

**Ex.**

1/3, 2/4, 5/6, 2/9

*Make Common Denominators and Equal Fractions*

1/3 = 12/36

2/4 = 18/36

5/6 = 30/36

2/9 = 8/36

*Order the Fractions with Common Denominators*

8/36, 12/36, 18/36, 30/36

*Write the Original Fraction*

2/9, 1/3, 2/4, 5/6

Now we will move on to Simplest Form Fractions, Mixed Number Fractions, Whole Number Fractions, and Comparing Fractions.

**Simplest Form** – Reduce the fraction to the Simplest Form.

* Ex.* 8/12 = 2/3

15/4 = 3 3/4

**Changing Fractions to Mixed Numbers or Whole Numbers** – Divide the Denominator in to the Numerator.

* Ex.* 16/5 = 3 1/5

**Changing Mixed Numbers to Fractions or Whole Numbers to Fractions** – Multiply the Denominator times the Whole Number. Then Add the Numerator and put your answer over the Original Denominator.

** Ex.** 6 1/5 = 31/5

**Comparing Fractions** – You will need to cross-multiply the fractions. Compare the products.

* Ex.* 2/3 3/5 2/3 is Greater Than 3/5

Now we will cover Adding Fractions, Subtracting Fractions, Multiplying Fractions, and Dividing Fractions.

**Adding Fractions with Same Denominators** – Add the Numerators and leave the Denominators the same.

* Ex.* 3/8 + 2/8 = 5/8

1/5 + 2/5 = 3/5

**Adding Fractions with Different Denominators** – If one Denominator will divide evenly into the other Denominator, change the Denominator to the highest Denominator. Then add. If it won’t divide evenly then multiply the two Denominators and that will give you your new Denominator. Then Add..

* Ex.* 1/4 + 1/8 = 2/8 + 1/8 = 3/8

2/3 + 1/2 = 2/5 + 1/5 = 3/5

**Subtracting Fractions** – Subtract Fractions the same way that you add them. Just subtract instead.

**Multiplying Fractions** – Multiply Numerator times Numerator and Denominator times Denominator.

* Ex.* 3/4 x 2/5 = 6/20

**Dividing Fractions** – Flip the second Fraction upside down and Multiply.

* Ex.* 1/3

– – – 1/3 x 5/2 = 5/6

2/5
