1.**

Write the next three natural numbers after 10999.**Solution:
**The next three natural numbers after 10999 are
11000, 11001 and 11002.

2.**

Write three whole numbers occurring just before
10001.**Solution:**

Three whole numbers occurring just before are:**
**10001 – 1 = 10000

10000 – 1 = 9999

9999 – 1 = 9998

Hence, three whole numbers occurring just before 10001 are 10000, 9999 and 9998.

Write the successor of:(a) 2440701

(b) 100199

(c) 1099999

(d) 2345670

**Solution:****
**(a) The successor of 2440701 is
2440701 + 1 = 2440702

Hence, the successor of 2440701 is 2440702.

(b) The successor of 100199 is 100199 + 1 = 100200

Hence, the successor of 100199 is 100200.

(c) The successor of 1099999 is 1099999 + 1 = 1100000

Hence, the successor of 1099999 is 1100000.

(d) The successor of 2345670 is 2345670 + 1 = 2345671

Hence, the successor of 2345670 is 2345671.

Write the predecessor of:(a) 94

(b) 10000

(c) 208090

(d) 7654321

**Solution:
**(a) The predecessor of 94 is 94 – 1 = 93

Hence, the predecessor of 94 is 93.

(b) The predecessor of 1000 is 10000 – 1 = 9999

Hence, the predecessor of 10000 is 9999.

(c) The predecessor of 208090 is 208090 – 1 = 208089

Hence, the predecessor of 208090 is 208089.

(d) The predecessor of 7654321 is 7654321 – 1 = 7654320

Hence, the predecessor of 7654321 is 7654320.

**Ex 2.1 Class 6 Maths Question
7.**

In each of the following pairs of numbers, state
which whole number is on the left of the other number on the number line. Also
write them with the appropriate sign (>, <) between them.(a) 530, 503

(b) 370, 307

(c) 98765, 56789

(d) 9830415, 10023001

**Solution:
**We know that the smaller number is always on the
left side of the greater number on the number line.

(a) 530, 503

Clearly, 503 is smaller than 530.

Thus, 503 will be on the left side of 530 on the number line.

Hence, 503 < 530 or 530 > 503

(b) 370, 307

Clearly, 307 is smaller than 370.

Thus, 307 will be on the left side of 370 on the number line.

Hence, 307 < 370 or 370 > 307

(c) 98765, 56789

Clearly, 56789 is smaller than 98765.

Thus, 56789 will be on the left side of 98765 on the number line.

Hence, 56789 < 98765 or 98765 > 56789

(d) 9830415, 10023001

Clearly, 9830415 is smaller than 10023001.

Thus, 9830415 will be on the left side of 10023001 on the number line.

Hence, 9830415 < 10023001 or 10023001 > 9830415

**Ex 2.1 Class 6 Maths Question
8.**
