Let 1/√2 be a rational number So 1/√2= p/q where p and q are co primes and q≠0 q/√2=p Squaring on both sides, q²/2=p² —(1) Here, q² is divisible by 2 so q is also divisible by 2 Let q=k Put value of q in equation (1) k²/2=p² Divide by 2 on both sides k²/4=p²/2 Here, p² is divisible by 2 so p is also divisible by 2 But we have assumed that p and q are co primes This contradiction has arisen due to our wrong assumption Hence 1/√2 is an irrational number

Let numerator be x Let denominator be y (x+2)/(y+2)=4/5 5x+10=4y+8 x=(4y-2)/5........(i) (x-4)/(y-4)=1/2 2x-8=y-4 2x=y+4......(ii) By putting eq.i in ii 2(4y-2)/5=y+4 (8y-4)/5=y+4 8y-4=5y+20 3y=24 y=24/3 y=8 x =[4(8)-2]/5 x=30/5 x= 6 The fraction is 6/8 =3/4
