Fractions — Like and Unlike — Lesson
🍉 Fractions — Like and Unlike 🍎
🌟 Hook: The Mango Party! 🥭
Imagine you and your friends have a big, juicy mango 🍈. You cut it into 4 equal pieces and eat 2 pieces. So, you ate 2/4 of the mango.
Now, your friend has a watermelon 🍉. She cuts it into 6 equal pieces and eats 3 pieces. She ate 3/6 of the watermelon.
Are your mango pieces and her watermelon pieces the same size? How do you compare these fractions? Let's find out!
📚 Core Concepts
What is a fraction? A fraction shows a part of a whole. It has two parts:
- Numerator (top number): How many parts we have.
- Denominator (bottom number): How many equal parts the whole is divided into.
Like Fractions: Fractions that have the same denominator (same bottom number).
Example: 3/7 and 5/7 are like fractions because both have denominator 7.
Unlike Fractions: Fractions that have different denominators (different bottom numbers).
Example: 2/5 and 3/8 are unlike fractions because denominators are 5 and 8.
Visual Table: Like vs Unlike Fractions
| Type | Fraction 1 | Fraction 2 |
|---|---|---|
| Like Fractions | 4/9 | 7/9 |
| Unlike Fractions | 3/4 | 5/6 |
📝 Key Formulas / Rules
Example: 5/11 and 7/11
Example: 2/3 and 4/5
💡 Did You Know?
Fractions were used in ancient India! The famous mathematician Aryabhata wrote about fractions more than 1,000 years ago! 🇮🇳
📝 Exam Tips
- Always check if fractions are like or unlike before adding or comparing.
- Do not forget to find the Least Common Denominator (LCD) for unlike fractions.
- Write fractions neatly — numerator on top and denominator below, separated by a line.
- Practice drawing fraction pies or bars to understand parts better.
- Board exam questions often ask to identify like/unlike fractions or to add like fractions.

2. UNLIKE FRACTIONS 🚶♂️🚶♀️
“Different Bottoms, Different Problems!”
When fractions have different denominators, they are unlike.
Example: 3/4 and 2/7 are unlike because 4 ≠ 7.

Unlike fractions, bottoms change,
Find LCM, then arrange!”
