Whole numbers on a number line

Let’s understand first what is a number line? A pictorial representations of numbers evenly marked on a straight line is known as a number line.

• To mark whole numbers on a number line draw a horizontal line and mark a point on it as 0.
• Extend this line towards right direction.
• Starting from 0, mark points 1, 2, 3, 4, 5, 6, 7, 8, 9….on a line at equal distance towards right side. • There is no whole number on the left of zero. Therefore zero is the smallest whole number.
• A whole number is greater than all the whole numbers which lie to the left of it on the number line.
• A whole number is less than all the whole numbers which lie to the right of it on the number line
• The number line also helps us to compare two whole numbers. i.e., to decide which of the two given whole numbers is greater or smaller.
• Therefore we can say that 5 is less than 9 and write 5 < We can also say that 5 is greater than 4 and write 5 > 4. Question: 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. 530, 503 (b) 370, 307 (c) 98765, 56789 (d) 9830415, 10023001

Solution

(a) 503 is on the left side of 530 on the number line.    530 > 503

(b) 307 is on the left side of 370 on the number line.   370 > 307

(c) 56789 is on the left side of 98765 on the number line.   98765 > 556789

(d) 9830415 is on the left side of 10023001 on the number line.  9830415 < 10023001
