Answers : Cbse 6th whole number worksheet

Sure! Here are the answers to the practice questions:

1.
   a) Predecessor of 52 = 52 – 1 = 51

      Successor of 52 = 52 + 1 = 53

   b) Predecessor of 99 = 99 – 1 = 98

      Successor of 99 = 99 + 1 = 100

2.
   Smallest 3-digit number = 100

   Largest 3-digit number = 999

3.
   a) 78 – 23 + 40 = 55 + 40 = 95

   b) 84 + 92 – 47 = 176 – 47 = 129

4.
   a) Product of 5 and 7 = 5 * 7 = 35

   b) Product of 9 and 0 = 9 * 0 = 0

5.
   a) Sum of 103, 122, and 56 = 103 + 122 + 56 = 281

   b) Sum of 187, 35, and 82 = 187 + 35 + 82 = 304

6.
   a) 3x + 7 = 25
      3x = 25 – 7
      3x = 18
      x = 18/3
      x = 6

   b) 4x – 6 = 18
      4x = 18 + 6
      4x = 24
      x = 24/4
      x = 6

7. The difference between the two whole numbers is 28, and the smaller number is 64.

   Let the larger number be ‘x’.
   x – 64 = 28
   x = 28 + 64
   x = 92

8. Shelly saved ₹85 each month for 9 months.
   Total amount saved = ₹85 * 9 = ₹765

9. A box contains 54 chocolates. If 18 chocolates are taken out,
   Chocolates left = 54 – 18 = 36

10. Divide 532 by 4.
    Quotient = 532 ÷ 4 = 133
    Remainder = 532 % 4 = 0

These are the solutions to the practice questions on whole numbers.

Certainly! Here are the answers to the questions:

1. The first 10 even whole numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20. Their sum is 2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 110.

2. The largest 4-digit even number is 9998. Subtracting 256 from it gives 9998 – 256 = 9742.

3. Multiplying 785 by 13 gives 10105. Subtracting 247 from it gives 10105 – 247 = 9868.

4. The predecessor of 365 is 365 – 1 = 364. The successor of 365 is 365 + 1 = 366.

5. The odd numbers between 200 and 230 are 201, 203, 205, 207, 209, 211, 213, 215, 217, 219, 221, 223, 225, 227, 229.

6. The smallest prime number greater than 30 is 31.

7. The sum of the first 12 odd whole numbers is 1 + 3 + 5 + 7 + 9 + 11+ 13 + 15 + 17 + 19 + 21 + 23 = 144. Subtracting 550 from it gives 144 – 550 = -406.

8. The square of 13 is 13^2 = 169. The square of 9 is 9^2 = 81. So, the difference between their squares is 169 – 81 = 88.

9. The prime factors of 8 are 2 x 2 x 2 = 2^3. So, the product of its prime factors is 2^3 = 8.

10. The largest prime number is 2, so dividing 189 by 2 gives 189 ÷ 2 = 94.5.

11. The least common multiple (LCM) of 12 and 16 can be found by listing their multiples: 

Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, …
Multiples of 16: 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240, …
From the listed multiples, we can see that the LCM of 12 and 16 is 48.

12. Subtracting 1 from any square number will always result in a “non-square” number.

13. Multiplying 543 by 9 gives 543 * 9 = 4887. Adding 567 to it gives 4887 + 567 = 5454.

14. The first 8 multiples of 7 are 7, 14, 21, 28, 35, 42, 49, 56. Their sum is 7 + 14 + 21 + 28 + 35 + 42 + 49 + 56 = 252.

15. When 1534 is divided by 7, the remainder is 1534 % 7 = 4.
