Comparison of Numbers

Comparison is required to find the greater, smaller and equal numbers among the given numbers. The common symbols for the comparison are;

> is called 'greater than';

< is called less than/;

= is called equal sign.

 

  •          Example:

Compare the given numbers and put suitable symbol between them. 5 kilometres ________ 4090               

(a) >                                                                 (b) <

(c) =                                                                 (d) All the above

(e) None of these

Ans.     (a)

Explanation: 5 km = 5 \[\times \] 1000 metre = 5000 metres. Therefore, option (a) is correct.

 

Rules for Comparison

 

1. A three digit number is always greater than a two digit number.

2. If two numbers have the same number of digits, then digits on the extreme left are compared and in this case, the number with greater digit is bigger.

3. If two numbers have the same number of digits and the extreme left digits are the same, then the second digit from the left side are compared and the process goes on.

 

  •           Example:

Which one of the following is not correct?

(a) 556 > 567                                                    (b) 554 < 555

(c) 598 = 598                                                    (d) All the above

(e) None of these

Ans.     (a)

Explanation: First two digits from left are same in all the options, except (A)

Therefore, (a) is the correct answer,

(a) >                                                                 (b) <
