the equation can be simplified as follows:- (1/a)+(1/b)=2. so 1/b= 2- (1/a), simplifying by taking LCM 1/b=(2a-1)/a. thus, flipping over the numerator and denominator on both sides we get b= a/(2a-1) This shows that by putting the value of b, the ratio a:b= a/ which is equal...

a + b = 2 ...........I a * b = 1 ...........II From equation II, we get a = 1/b .............III put this value in equation I ie. 1/b + b = 2 (1 + b*b) / b = 2 1 + b*b = 2b b*b - 2*b + 1 = 0 (b - 1)(b - 1) = 0 b - 1 = 0 b = 1 Put this...
