Q6: Round off the following numbers to the nearest tens:
(a) 13,528
(b) 3,542
(c) 174

Multiplication Class 6 Worksheet Maths

Sol: Here's the general rule for rounding:

  • Number >= 5: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
  • Number < 5: If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Therefore, applying these rules, we get:
(a) 13,528 = 13,530
(b) 3,542 = 3,540
(c) 174 = 170

Q8: Estimate each of the following products by rounding off each number to the nearest tens:
(a) 52 x 43
(b) 63 x 52

Sol: Here's the general rule for rounding:

  • Number >= 5: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
  • Number < 5: If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Therefore, applying these rules, we get:
(a) 52 x 43 = 50 x 40 = 2000
(b) 63 x 52 = 60 x 50 = 3000

Q9: Find the product of the place-values of 6 in 6,965 ______.
Multiplication Class 6 Worksheet Maths


Sol: The place value of 1st 6 in 6,965 is at thousand's place.
=> First place value of 6 = 6000
The place value of 2nd 6 in 6,965 is at ten's place.
=> Second place value of 6 = 6000
Product of the place values of 6 in the number 6,965 = 6000 x 60 = 360000

Q11: Find the product of the greatest 2-digit number and the smallest 4-digit number ______.

Sol: Greatest 2-digit no. = 99
Smallest 4-digit no. = 1000
Therfore, the product of the greatest 2-digit number and the smallest 4-digit number = 1000 x 99 = 99000.

Q12: Round off the following numbers to the nearest thousands:
(a) 4,550
(b) 87,083
(c) 9,155


Sol: To round to the nearest thousand, we look at the last three digits.

  •  If these digits are 500 or greater, then we round the thousands digit up 
  • If they are less than 500, then we round down, keeping the thousand's digit the same.
    Multiplication Class 6 Worksheet Maths

Therefore, applying these rules, we get:
(a) 4,550 = 5000
(b) 87,083 = 90000
(c) 9,155 =  9000

Q13: Find the following products mentally:
(a) 995 x 995 ______.
(b) 705 x 705  ______.
(c) 499 x 491 ______.

Sol: (a) 995 x 995 = 990,995.
(b) 705 x 705 = 497,025.
(c) 499 x 491 = 245,009

Q14: A transistor costs Rs 1,642. Find the cost of 95 such transistors. 
Multiplication Class 6 Worksheet Maths

Sol: Cost of one Transistor = Rs 1,642
Total number of transistors = 95
Cost of 95 Transistors = 1642 x 95 = 155,990

FAQs on Multiplication Class 6 Worksheet Maths

1. How can multiplication help in solving real-life problems?
Ans. Multiplication can help in solving real-life problems by quickly calculating the total when dealing with groups of items, finding the total cost of multiple items, or determining the area of a rectangular space by multiplying its length and width.
2. What are some strategies to memorize multiplication tables effectively?
Ans. Some strategies to memorize multiplication tables include practicing regularly, using mnemonic devices, breaking down tables into smaller chunks, and using flashcards or online games for reinforcement.
3. How can multiplication be used in division problems?
Ans. Multiplication is the inverse operation of division. When dividing two numbers, you can use multiplication to check your answer by multiplying the quotient with the divisor to see if it equals the dividend.
4. Can multiplication be used for scaling or resizing objects?
Ans. Yes, multiplication can be used for scaling or resizing objects. By multiplying the dimensions of an object by a certain factor, you can increase or decrease its size while maintaining its proportions.
5. How does multiplication relate to addition and subtraction?
Ans. Multiplication is a quicker way of adding multiple numbers together. For example, instead of adding 5+5+5+5, you can multiply 5 by 4 to get the same result. Subtraction can be seen as the inverse operation of addition when dealing with multiplication.
