Introduction to Fractions

Fractions, jo ki bhinn bhi kehte hain, ek number ko parts mein divide karte hain. Inme do main parts hote hain: numerator (upper part) aur denominator (lower part). For example, 1/2 mein 1 numerator hai aur 2 denominator hai.

Types of Fractions

Fractions ke kai prakar hote hain. Inhe samajhna bahut zaroori hai.

• Proper Fractions: Jab numerator denominator se chota hota hai, jaise 3/5.
• Improper Fractions: Jab numerator denominator se bada ya equal hota hai, jaise 7/4.
• Mixed Fractions: Ek whole number aur fraction ka combination, jaise 2 1/3.

Operations on Fractions

Fractions par various operations perform kiye ja sakte hain. Aaiye inhe step-by-step dekhte hain.

Addition of Fractions

Fractions ko add karne ke liye, pehle denominator same karna hota hai. Agar denominators same hain, to numerators directly add kar do. Example: 1/4 + 2/4 = 3/4. Agar denominators different hain, to LCM nikal ke fractions ko equivalent banaye.

Subtraction of Fractions

Subtraction bhi addition ki tarah hota hai. Denominators same karo, fir numerators subtract karo. Example: 5/6 - 2/6 = 3/6, jisko simplify karke 1/2 kar sakte hain.

Multiplication of Fractions

Fractions ko multiply karna simple hai. Directly numerators ko multiply karo aur denominators ko multiply karo. Example: 2/3 * 3/5 = (2*3)/(3*5) = 6/15, jisko simplify karke 2/5 milta hai.

Division of Fractions

Division mein, second fraction ka reciprocal leke usse multiply karte hain. Example: 2/3 ÷ 4/5 = 2/3 * 5/4 = 10/12 = 5/6 after simplification.

NCERT Examples and Solutions

Ab hum kuch NCERT textbook se examples lete hain aur unhe solve karte hain.

Example 1: Adding Mixed Fractions

Question: 2 1/3 + 3 2/5 ko solve karo. Pehle mixed fractions ko improper fractions mein badlo: 7/3 + 17/5. Ab denominators ka LCM lo, jo 15 hai. Equivalent fractions banao: 35/15 + 51/15 = 86/15. Isse mixed fraction mein: 5 11/15.

Example 2: Word Problem

Ek cake ka 1/4 part Rahul ne khaya aur 1/3 part Sita ne khaya. Kitna cake bacha? Solution: Total khaya gaya part = 1/4 + 1/3. LCM of 4 and 3 is 12. So, 3/12 + 4/12 = 7/12. Bacha hua cake = 1 - 7/12 = 5/12.

Practice Tips

Fractions ko acchi tarah samajhne ke liye regular practice karo. NCERT exercises solve karo aur real-life situations mein apply karo. Hinglish mein explanations se aap easily concepts grasp kar sakenge.
