Rule 1. A 2-digit number is always greater than a 1-digit number.

T O T O T O T O
examples: a. b.
4 2 > 9 5 4 > 7

Rule 2. When two 2-digit numbers are compared, the number with the

greater tens digit is the greater number.

examples: a. T O T O b. T O T O
8 6 > 5 1 5 9 > 4 7

> >

Thus, 86 > 51 or 51 < 86 Thus, 59 > 47 or 47 < 59

Rule 3. When two 2-digit numbers have the same tens digit, the number with

the greater ones digit is the greater number.

examples: a. T O T O b. T O T O

5 4 > 5 2 6 9 > 6 8

= =
> >

Thus, 54 > 52 or 52 < 54 Thus, 69 > 68 or 68 < 69

ordering numbers

We have already learnt how to arrange numbers in ascending and
descending order.

Let us arrange the numbers 75, 68, 84, 47 and 90 in T O
descending order. 7 5

We know that in descending order, the numbers are 6 8
arranged from the greatest to the smallest. 8 4

So, the given numbers in descending order are 4 7 Smallest

90 > 84 > 75 > 68 > 47 9 0 Greatest
