Class 5 Mathematics Notes, Exercise 3, Q.No. 2, Unit-1, Whole Numbers and Operations (New Book/New Syllabus Based on Single National Curriculum Pakistan 2022 and onwards)

Q. Divide the following numbers by 10, 100, 1 000.

a)     49 000       b)    78 000          c)    65 000

d)    597 000      e)     210 000  

Key Fact:

• When we divide a whole number by 10, we remove one zero to the right-side of the number
• When we divide a whole number by 100, we remove two zero to the right-side of the number
• When we divide a whole number by 1 000, we remove three zero to the right-side of the number

Solution: 

a)  49 000

49 000 ÷ 10 =  4 900

49 000 ÷ 100 = 490

49 000 ÷ 1 000 = 49

b)    78 000

78 000 ÷ 10 =  7 800

78 000 ÷ 100 = 780

78 000 ÷ 1 000 = 78

c)    65 000

65 000 ÷ 10 =  6 500

65 000 ÷ 100 = 650

65 000 ÷ 1 000 = 65

d)    597 000

597 000 ÷ 10 = 59 700 

597 000 ÷ 100 = 5 970

597 000 ÷ 1 000 = 597

e)     210 000  

210 000 ÷ 10 = 21 000

210 000 ÷ 100 = 2 100

210 000 ÷ 1 000 = 210
