Pictograph data ko chitron se dikhaata hai. Yahan ek symbol har class ke eco club ka lagaaya ek ped hai. Ek nazar mein: Class 6C ne sabse zyada lagaaye, aur 6E ne sabse kam.

Ek symbol kai ke barabar ho sakta hai. School library mein ek book symbol = 10 books li gayin. 6A ke 4 symbols, to 4 × 10 = 40 books. 6B ke saadhe teen symbols: 30 + 5 = 35 books.

4 × 10 = 40 · 3½ × 10 = 35 · 2 × 10 = 20

Pictograph banana: Kabir ne school mein khadi cycles gini: Somvaar 40, Mangalvaar 45, Budhvaar 25, Guruvaar 30. Har cycle ka ek symbol banane mein bahut der lagegi! Isliye usne key 1 symbol = 5 cycles chuni.

40 ÷ 5 = 8 · 45 ÷ 5 = 9

Key: ek symbol = 10 aam. 3½ symbols kitne aam dikhaate hain?

  2. 35
  3. 40
  4. 350

35. 3 × 10 = 30, aur 10 ka aadha 5: 30 + 5 = 35.

Socho

Ek symbol = 10 cycles ho, to 42 cycles kaise dikhaoge? Mushkil kya hai?

Ek answer

42 matlab 4 symbols aur ek ka do-dasvaan hissa. Itna chhota hissa banana mushkil hai, isliye lagbhag 4 symbols tak round karte hain, ya 2 jaisi key chunte hain jo numbers ko poora bhaag de.
