Question

1 write any three rational numbers
2 explain ration numbers in your words with examples.

Answer 1

THREE RATIONAL NUMBERS ARE: 3/4 , 2 , -29/7
 
RATIONAL NUMBERS ARE THOSE NUMBERS WHICH CAN BE WRITTEN IN THE FORM OF p/q WHERE q IS NOT EQUAL TO ZERO. RATIONAL NUMBERS ARE ALWAYS IN THE SIMPLEST FORM, THAT IS, THEY DO NO HAVE ANY OTHER COMMON FACTOR THAN 1. THEY INCLUDE NATURAL NUMBERS, WHOLE NUMBERS AND INTEGERS.

Answer 2

Three rational numbers are: 5/7, -10/23, 57 

A rational number is a number which can be written as $\frac{p}{q}$ where p and q are integers and they are co-prime.
- A rational number can always be written as p/q. 57 can be written as 57/1.
- Both p and q should be integers. That's why though we can write √2 as √2/1, it is not a rational number as √2 is not an integer.
- Both p and q are co-prime which means p and q have only one common factor, which is 1. If there is any other common factor, then it can be further reduced. 
For example, 10/14 can be written as 5/7.
