How many rational number between any two equal number |
|
Answer» Infinity number We can find as many as numbers we want between any two numbers. For Eg:- The rational numbers between 1/3 and 1/2 are 201/600, 202/600, 203/600, 204/600 ...................... It depends on the denominator which we take, like here I took 600 as the denominator, we can take any number as the denominator which is divisible to 2 and 6. We can insert infinitely many rational numbers between any two rational numbers. This property of rational numbers is known as the dense property.How to find out some rational numbers lying between two given rational numbers, say between -4/7 and 2/7. The four rational numbers -3/7, -2/7, -1/7, 0/7 and 1/7 lies between -4/7 and 2/7. |

Prove √2 is irrational |
|
Answer» Yes Let us assume √2 is rational number.a rational number can be written into he form of p/q√2=p/qp=√2qSquaring on both sidesp²=2q²__________(1).·.2 divides p² then 2 also divides p.·.p is an even numberLet p=2a (definition of even number,\'a\' is positive integer)Put p=2a in eq (1)p²=2q²(2a)²=2q²4a²=2q²q²=2a².·.2 divides q² then 2 also divides qBoth p and q have 2 as common factor.But this contradicts the fact that p and q are co primes or integers.Our supposition is false.·.√2 is an irrational number. |
