Sahil ki maa pizza ko 8 barabar slices mein kaatti hain. Har slice pizza ka 1/8 hai. Sahil 3 slices khaata hai: yaani 1/8 + 1/8 + 1/8 = pizza ka 3/8.

1/8 + 1/8 + 1/8 = 3/8

3/8 jaise fraction mein, neeche ka number (denominator) batata hai whole kitne barabar hisson mein kata. Upar ka number (numerator) batata hai unme se kitne hisse liye.

3/8 = 3 parts of size 1/8

Jab saare hisse le liye, to poora whole mil gaya: 8/8 = 1. Waise hi 4/4 = 1 aur 2/2 = 1.

4/4 = 1

Fraction kisi group ka hissa bhi ho sakta hai. Nisha ke paas 12 kanche hain aur unka 1/4 neela hai. 3-3 ke 4 barabar group banao: ek group neela hai, to 3 kanche neele hain.

12 ÷ 4 = 3

Explore: strip aur gole par fractions rango. Picture ke neeche wala number batata hai tumne kya banaya.

1. Strip ka 3/5 rango.
2. Poori strip rango. Ye kaunsa fraction hai?
3. Gole ka 5/8 rango.

Yaad rakho

• Numerator (upar) = kitne hisse liye. Denominator (neeche) = whole mein kitne barabar hisse.
• 3/8 matlab 1/8 ke 3 unit. Saare hisse milkar 1: 8/8 = 1.

Quick check

Chocolate bar ke 10 barabar tukde hain. Divit 7 tukde khaata hai. Usne bar ka kitna hissa khaaya?

1. 7/10
2. 10/7
3. 3/10
4. 7/3

Socho

Farhan kehta hai strip ka rangeen hissa 1/3 hai kyunki teen mein se ek hissa rangeen hai. Par teeno hisse ek jitne nahi hain. Kya wo sahi hai?
