Aasan Tareeqa — Fractions ko Compare karna (Class 4)

Chalo step by step samajhtay hain simple English words may.

Given fractions:

2/9 8/9 5/6 1/3

Step 1 — Maqsad Samjho

Hamein yeh pata karna hai ke kaunsi fraction chhoti hai aur kaunsi badi.

Step 2 — Easy Rule (Jab Denominator same ho)

Agar neeche wala number (denominator) same ho to sirf upar wala number (numerator) dekho. Chhota numerator → chhoti fraction.

Example: 2/9 aur 8/9 — dono ka denominator 9 hai. 2 < 8 → 2/9 chhoti, 8/9 badi.

Step 3 — Jab Denominators different ho (Cross Multiplication)

Do fractions ko compare karne ka simple tareeqa:

1. Pehle fraction ke numerator ko doosri fraction ke denominator se multiply karo.
2. Phir doosri fraction ke numerator ko pehli fraction ke denominator se multiply karo.
3. Jiska answer chhota ho, wo fraction chhoti hoti hai.

Step 4 — Example 1

Compare karo: 2/9 aur 1/3

• 2 × 3 = 6
• 1 × 9 = 9

Ab dekho: 6 chhota hai 9 se →

2/9 < 1/3

Step 5 — Example 2

Compare karo: 1/3 aur 5/6

• 1 × 6 = 6
• 5 × 3 = 15

6 chhota hai 15 se →

1/3 < 5/6

Step 6 — Example 3

Compare karo: 5/6 aur 8/9

• 5 × 9 = 45
• 8 × 6 = 48

45 chhota hai 48 se →

5/6 < 8/9

Step 7 — Sabko Combine karo

Ab sab comparisons ke baad result ye hai:

2/9 < 1/3 < 5/6 < 8/9

Final Answer

Ascending (smallest to biggest):

2/9 < 1/3 < 5/6 < 8/9

Descending (biggest to smallest):

8/9 > 5/6 > 1/3 > 2/9

Easy Tips for Kids

• Agar denominator same ho to numerator dekho — bada numerator matlab badi fraction.
• Agar denominators alag ho to cross multiply karo jaisay humne upar kiya.
• Har step slow kar ke karo aur result zor se padh kar samjho.
