Difference between even and odd prime and rational  numbers.

Even numbers: 

                            Even numbers are those numbers which can be divided by 2.For example 2,4,6,8,1000 200 250 are the example of even no which are completely divisible by 2.

odd numbers:

                          The numbers which can not be divided by 2 are called odd numbers.For example the number 3,5,7,11,21,33,99,9999,73 are odd because they are not divisible by 2.
You can differentiate a number is odd or even you have to divide that no by 2.If it is completely divisible by 2 it means it is even.IF it is not divisible by 2 than its odd.

Prime numbers:

                              A prime no is a positive number greater than 1 that is divisible by itself or by 1.
1 is not a prime no because it has only one factor but prime numbers have two factors.For example 2,is divisible by 1 and 2 it self so 2 has two factors that are 1 and 2.but 1 has only 1 factor that is 1.

Rational numbers:

                           A number which which can be written in form of p/q,where p and q are integers and q is not equal to zero.For example 22/7,4 are example of rational numbers.

Difference between Micro economic and Macro economics. Macro economics.                               Macro economics looks at the economy as a whole or its major components of the economy.     For example:All consumers,Federal government,US economy Micro economics.                               Micro economics focuses on a specific economic unit.      For example: An individual household,firm or industry. Both individual and society face economic problems. Because They need to make choices because wants exceed needs. Example of economic problems faced by individual's and society's. Individual's economic problems. The budget line Society's economic problems. land. labor. capital.

What is the greatest common divisor and how to find the greatest common divisor of two numbers.

Greatest common divisor:                                                The greatest common divisor of  two integers a and b.Which are not both zero is the largest integer that divides both a and b.Which is written as (a,b) and is also written as,     gcd(a,b) The  greatest common divisor is a number which should divide the number a and b,Now we find the gcd of some numbers as under. For example:  Find the gcd of  24 and 30. First find the divisors of  24 and 30  we have.         24 = 1,2,3,4,6,8,12,24         30 = 1,2,3,5,6,10,15,30 Now we seen that there are many common divisors of 24 and 30.these are (1,2,3,6) but we have to chose the largest number which is a common divisor of 24 and 30.Here 6 is the largest integer that is the greatest common divisor of both 24 and 30.So 6 is the greatest common divisor of 24 and 30. Another example:      find the gcd of    20 and 35.            Factors of 20 and 35. 20=1,2,4,5,10,20 35=1,5,7,35 So the greatest com
