Gauri ki daadi Gauri aur uske bhai ke liye ek bada thepla banati hain. Barabari ke liye wo use 2 barabar hisson mein kaatti hain. Har bachche ko aadha milta hai, likhte hain 1/2.

Agar 3 bachche baantein to har ek ko 1/3 (ek tihaai) milta hai. 4 baantein to 1/4 (ek chauthai). 1/2, 1/3 ya 1/4 jaisa tukda fractional unit kehlata hai: whole ke kai barabar hisson mein se ek.

Barabar hona zaroori hai! Agar roti ek bade aur ek chhote tukde mein phat jaaye, to koi bhi tukda 1/2 nahi. Do tukde tabhi aadhe hain jab bilkul ek jitne hon.

Jitne zyada log ek whole baantein, har hissa utna chhota. To 1/2 > 1/3 > 1/4 > 1/5 … Neeche ka number bada matlab tukda chhota.

1/2 > 1/3 > 1/4 > 1/5 > 1/6

Do cheezein, teen dost. Kabir, Zoya aur Tenzin 2 chikki bars barabar baant-te hain. Har bar ko 3 barabar hisson mein kaato; har dost har bar se ek hissa leta hai. Har ek ko 1/3 + 1/3, yaani bar ka 2/3 milta hai.

2 ÷ 3 = 2/3 each

Explore: imaandaar kaatne wale bano. Barabar hisson ki ginti chuno aur ek hissa rango.

1. Gola 4 doston ke liye kaato aur ek dost ka hissa rango.
2. Ab dikhao jab 6 dost baantein to ek ka hissa.
3. Kaunsa hissa bada hai, 1/3 ya 1/8? Bada wala rango.

Yaad rakho

• Fractional unit whole ke kai barabar hisson mein se ek hai: 1/2, 1/3, 1/4 …
• Zyada barabar hisse → chhota unit. 1/3, 1/5 se bada hai.

Quick check

5 dost ek tarbooz barabar baant-te hain. Har ek ko kitna milta hai?

2. 5
3. 5/1
4. 1/4

Socho

Do kaagaz ki strips ek jitni hain. Ira ek ko 4 barabar hisson mein modti hai aur doosri ko 8 mein. Kis strip ke hisse bade hain, aur ek bade hisse mein kitne chhote hisse samaate hain?
