Answer 1

Answer:

1. 84,08999.

2. 90,000

3. three

4. 9,18,500

Answer 2

1) Write the predecessor of 84,09000

• 8408999

2) Find the difference between the largest 4-digit number and the largest 5-digit number.

• $9999 - 99999 = - 90000$

3) How many whole numbers are there upto 1000?

• 1000+ 1 = 1001

4) Find the product of 2 x1,837 x 250.

• $2 \times 1837 \times 250 = 918,500$

5) What type of number is the product of two even numbers?

• always even

6) Find the value of 4,560 - 120 x (200-40).

• $4,560 - 120 \times (200-4) \\ = 4560 - 120 \times 196 \\ = 4560 - 23,520 \\ = - 18,960$

7) Find the value of 450 x 7+750 x 7.

• $450 \times 7 + 750 \times 7 \\ = 3150 + 5250 \\ = 8400$

8) Out of any two whole numbers on the number line, the number on the right of the other number is

greater. Is it true?

• True

9) Name the property used : 15 x 104 =15x (100+ 4) = 15 x 100+ 15 x 4.

• Distribute property

10) Addition and multiplication are commutative for whole numbers. Is it true?

• True

11) Find the value of 625+25 -0.

• $625 + 25 + 0 = 650$

12) Find : 500+20+5+ successor of 0.

• 521

13) Is there any natural number which when added to itself gives that number?

• No

14) Is there any whole number which when added to itself gives that number?

• Yes (0)

15) Use the most convenient combination to find the sum. 7,013 +22+2345 + 287 +655 +678

• $7,013 +22+2345 + 287 +655 +678 = 11000$

16) What should be subtracted from 8,203 to get the result as 1,913?

• 6290

17) Find : Predecessor and the successor of 11 - Successor and the Predecessor of 9.

• Predecessor of 11 = 10 ; Successor of 11 = 12 ; Predecessor of 9 = 8 ; Successor of 9 = 10

18) Some number can be arranged as squares. Write down the first 4 square numbers.

• 1, 4, 9, 16

19) Find the value of 8,165 x 169-8,165 x 69.

• $8,165 \times 169-8,165 \times 69. \\ = 1,379,885 - 563,385 \\ = 1,943,270$

20) Is the product of two odd whole numbers an even whole number? not true false only answer the following question

• False
