In 3/5, the numerator is 3 (the top number)
This represents how many parts are taken
In 3/5, the denominator is 5 (the bottom number)
This represents the total number of equal parts
3/5 means 3 parts out of 5 total equal parts
Draw a rectangle divided into 5 equal parts, shade 3 of them
Numerator: 3 (parts taken)
Denominator: 5 (total equal parts)
Meaning: 3 out of 5 equal parts of the whole
• Position Rule: Numerator is always above the fraction bar
• Count Rule: Denominator tells the total number of equal parts
• Part Rule: Numerator tells how many parts are being used
A pizza is cut into 8 equal slices. If 5 slices are eaten, write the fraction representing the eaten part.
Identify numerator and denominator, and explain what each represents.
Word Problems: Convert real situations into fractions
Total vs. Part: Denominator = total, Numerator = part taken
- Identify the total number of equal parts
- Identify how many parts are taken/used
- Write as fraction: taken/total
- Label numerator and denominator
Pizza is cut into 8 equal slices → Total = 8
5 slices are eaten → Taken = 5
Fraction = Eaten/Total = 5/8
Numerator = 5 (eaten slices), Denominator = 8 (total slices)
Fraction: 5/8
Numerator: 5 (slices eaten)
Denominator: 8 (total slices)
• Real-World Rule: Numerator = parts taken, Denominator = total parts
• Context Rule: Read the problem carefully to identify what's taken vs. total
• Order Rule: Always numerator over denominator
Use the strategies learned in the video to determine which is larger.
Explain your reasoning step by step.
Like Denominators: When denominators are the same, compare numerators
Unlike Denominators: Find common denominator or use visual models
- Check if denominators are the same
- If different, find common denominator
- Convert fractions to equivalent forms
- Compare numerators of equivalent fractions
2/3 has numerator 2, denominator 3
3/4 has numerator 3, denominator 4
LCM of 3 and 4 is 12
2/3 = 8/12, 3/4 = 9/12
8 < 9, so 8/12 < 9/12
Therefore: 2/3 < 3/4
3/4 is larger than 2/3
When converted to equivalent fractions with common denominator 12: 2/3 = 8/12 and 3/4 = 9/12
Since 9 > 8, then 3/4 > 2/3
• Common Denominator Rule: Convert fractions to compare when denominators differ
• Equivalent Fractions: Multiply numerator and denominator by same number
• Comparison Rule: With same denominator, compare numerators directly

Explain what each number represents.
Numerator: 7 (parts taken)
Denominator: 9 (total equal parts)
Meaning: 7 out of 9 equal parts of the whole
Which is larger and why?
Both fractions have the same denominator (7)
Compare numerators: 3 vs 4
Since 4 > 3, then 4/7 > 3/7
Write the fraction representing the eaten part after watching the real-world video.
Total pieces: 10 (denominator)
Eaten pieces: 3 (numerator)
Fraction: 3/10
Question: I watched the video about numerator and denominator, but I still get confused about which is which. Any tips?
Answer: Great question! Here are some helpful memory tricks:
- "Numerator = Number Up": The numerator is always on top (up)
- "Denominator = Down": The denominator is always on the bottom (down)
- Think of "Down-ominator": Both start with "D" and both are at the bottom
- Read it as "numerator over denominator": This reinforces the order
Practice with the video examples by pausing and identifying numerator and denominator in each fraction shown.
Question: The video showed how to compare fractions with the same denominator, but what about different denominators?
Answer: When denominators are different, you need to find a common denominator:
- Find LCM: Look for the least common multiple of the denominators
- Convert: Change both fractions to equivalent fractions with the common denominator
- Compare: Now you can compare numerators directly
Example: To compare 2/3 and 3/4, convert to 8/12 and 9/12. Since 9 > 8, then 3/4 > 2/3.
Question: How can I make sure my child is getting the most out of the fraction videos?
Answer: Here are strategies to maximize video learning effectiveness:
- Prepare materials: Have paper, pencil, and manipulatives ready
- Encourage note-taking: Write down key concepts and examples
- Pause for practice: Stop the video to work through examples
- Ask questions: Discuss the concepts after each video
- Apply immediately: Do practice problems right away
- Replay as needed: Rewatch difficult concepts
The key is active engagement rather than passive viewing!
