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

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

a)     381           b)    4 090          c)    97 509

d)    269 472      e)     852 118  

Key Fact:

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

Solution: 

a)     381

381 ｘ 10 = 3 810 

381 ｘ 100 = 38 100

381 ｘ 1 000 = 381 000 

b)    4 090

4 090 ｘ 10 = 40 900 

4 090 ｘ 100 = 409 000

4 090 ｘ 1 000 = 4 090 000 

c)    97 509

97 509 ｘ 10 = 975 090 

97 509 ｘ 100 = 9 750 900

97 509 ｘ 1 000 = 97 509 000 

d)    269 472

269 472 ｘ 10 = 2 694 720 

269 472 ｘ 100 = 26 947 200

269 472 ｘ 1 000 = 269 472 000 

e)     852 118  

852 118 ｘ 10 = 8 521 180 

852 118 ｘ 100 = 85 211 800

852 118 ｘ 1 000 = 852 118 000 

Similar Question:

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

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

d)    597 000      e)     210 000  

Solve the following.

a)  624 ｘ 23       b)   2 456 ｘ 90     c)   1 092 ｘ 981

d)  78 543 ｘ 49   e)  45 201 ｘ 561  f)   111 256 ｘ 342

f)  790 902 ｘ 643  g)   356 219 ｘ 101

Solve the following.

a)  13 440 ÷ 15    b)   86 449 ÷ 29   c)   32 536 ÷ 56
d)  47 088 ÷ 48    e)  56 780 ÷ 20    f)   26 166 ÷ 98
g)  73 810 ÷ 11    h)   64 454 ÷ 32
