Meher apni pencil naapna chahti hai, par uski naapne wali strip par sirf whole ke nishaan hain. Pencil 1 strip se chhoti hai. To wo strip ko 4 barabar hisson mein modti hai: pencil unme se 3 tak pahunchti hai. Uski pencil strip ki 3/4 hai.

3 × 1/4 = 3/4

Fractional units whole numbers ke beech ki cheezein naapne mein madad karti hain. Aadha metre, chauthai kilo, paune ghanta: sab kisi unit ke fractions hain.

Kisi lambai ka fraction dhoondhne ke liye pehle ek unit dhoondo. 20 cm ka 1/4: 20 cm ko 4 barabar hisson mein baanto → 5 cm. Phir 20 cm ka 3/4 = 3 × 5 = 15 cm.

20 ÷ 4 = 5 → 3 × 5 = 15 cm

Ulta socho: 3 m ribbon se 1/4 m ke kitne tukde milenge? Har metre se 4 tukde, to 3 m se 12 tukde.

3 × 4 = 12

Explore: ye naapne wali strip 1 unit lambi hai. Barabar hisson ki ginti chuno aur har cheez ki lambai rango.

1. Rubber 1/2 unit lamba hai. Uski lambai rango.
2. Crayon 2/3 unit lamba hai. Tihaai se rango.
3. Chaabi 5/6 unit lambi hai. Rango.

Yaad rakho

• Fractional units whole units ke beech ki lambai naapti hain.
• Kisi cheez ka k/d: d se bhaag do (ek unit), phir k se guna karo.
