Greetings, fellow math enthusiasts! Are you struggling to grasp the concept of subtracting fractions? Do you find yourself lost and confused when faced with a word problem that involves subtracting fractions? If so, donβt worry! Youβve come to the right place. In this comprehensive guide, we will be exploring the world of subtracting fractions, step by step. By the end of this article, you will have the skills and knowledge you need to master subtracting fractions and ace your next math test.

## π Understanding the Basics of Fractions

Before we dive into subtracting fractions, letβs first review the basics of fractions. A fraction represents a part of a whole, and it consists of two parts: the numerator and the denominator. The numerator is the number on the top of the fraction, and the denominator is the number on the bottom. For example, in the fraction 3/4, 3 is the numerator and 4 is the denominator. Fractions can be equivalent, meaning they represent the same amount, even if the numerators and denominators are different.

### π€ Frequently Asked Questions About Fractions:

Question | Answer |
---|---|

What is a fraction? | A fraction is a part of a whole, consisting of a numerator and a denominator. |

What is the numerator? | The numerator is the number on top of the fraction. |

What is the denominator? | The denominator is the number on the bottom of the fraction. |

What is an equivalent fraction? | An equivalent fraction represents the same amount as another fraction, even if the numerators and denominators are different. |

What is a proper fraction? | A proper fraction has a numerator that is smaller than its denominator. |

What is an improper fraction? | An improper fraction has a numerator that is greater than or equal to its denominator. |

What is a mixed number? | A mixed number is a combination of a whole number and a fraction. |

## π© How to Subtract Fractions: Step-by-Step Guide

Now that we have reviewed the basics of fractions, letβs move on to subtracting fractions. To subtract fractions, we need to have a common denominator. A common denominator is a multiple of both denominators. Hereβs a step-by-step guide to subtracting fractions:

### Step 1: Find a Common Denominator

To subtract fractions, we need to have a common denominator. To find a common denominator, we need to find the least common multiple (LCM) of both denominators. The LCM is the smallest number that is a multiple of both denominators. Once we have the LCM, we can convert both fractions into equivalent fractions with the same denominator.

### Step 2: Convert the Fractions

Once we have a common denominator, we can convert both fractions into equivalent fractions with the same denominator. To do this, we need to multiply both the numerator and denominator of each fraction by the same number. For example, if we have the fractions 1/4 and 3/8, and we find that the LCM is 8, we can convert the first fraction to 2/8 and the second fraction to 3/8.

### Step 3: Subtract the Numerators

Now that both fractions have the same denominator, we can subtract the numerators. To do this, we simply subtract the numerators and write the result over the common denominator. For example, if we have the fractions 2/8 and 3/8, we can subtract the numerators (2-3= -1) and write the result over the common denominator (8), giving us -1/8.

### Step 4: Simplify the Result

If the result is an improper fraction, we can simplify it by dividing the numerator and denominator by their greatest common factor (GCF). If the result is a mixed number, we can convert it to a mixed number by dividing the numerator by the denominator and writing the remainder over the denominator.

Question | Answer |
---|---|

What is a common denominator? | A common denominator is a multiple of both denominators. |

What is the least common multiple (LCM)? | The LCM is the smallest number that is a multiple of both denominators. |

How do you convert fractions to have the same denominator? | To convert fractions to have the same denominator, we need to find their least common multiple and multiply both the numerator and denominator of each fraction by the same number. |

What do you do after finding a common denominator? | After finding a common denominator, we can subtract the numerators and write the result over the common denominator. We can simplify the result by dividing the numerator and denominator by their greatest common factor (GCF). |

Can you subtract fractions with different denominators? | No, you cannot subtract fractions with different denominators. You need to first find a common denominator. |

What is the difference between a proper fraction and an improper fraction? | A proper fraction has a numerator that is smaller than its denominator, while an improper fraction has a numerator that is greater than or equal to its denominator. |

How do you convert an improper fraction to a mixed number? | To convert an improper fraction to a mixed number, you need to divide the numerator by the denominator and write the remainder over the denominator. |

## π Putting It All Together: Practice Examples

Now that you understand the process of subtracting fractions, itβs time to put your skills to the test! Here are some practice examples to help you master the art of subtracting fractions:

Example 1:

5/6 β 2/3 = ?

Step 1: Find a common denominator

Denominators | Factors | LCM |
---|---|---|

6 | 2Γ3 | |

3 | 3 | |

The LCM is 6. |

Step 2: Convert the fractions

5/6 = 5/6 x 1 = 5/6 x 2/2 = 10/12

2/3 = 2/3 x 2/2 = 4/6

Step 3: Subtract the numerators

10/12 β 4/6 = (10-8)/12 = 2/12 = 1/6

Step 4: Simplify the result

The result is already in its simplest form.

Example 2:

2/5 β 1/4 = ?

Step 1: Find a common denominator

Denominators | Factors | LCM |
---|---|---|

5 | 5 | |

4 | 2Γ2 | |

The LCM is 20. |

Step 2: Convert the fractions

2/5 = 2/5 x 4/4 = 8/20

1/4 = 1/4 x 5/5 = 5/20

Step 3: Subtract the numerators

8/20 β 5/20 = 3/20

Step 4: Simplify the result

The result is already in its simplest form.
