Answer:

x = 4/3 , 3/4

Step-by-step explanation:

Let the number be x

Reciprocal of number = \frac{1}{x}

We are given that Sum of a number and its reciprocal is 25/12.

So, x+\frac{1}{x}=\frac{25}{12}

\frac{x^2+1}{x}=\frac{25}{12}

12x^2+12=25x

12x^2-25x+12=0

12x^2-9x-16x+12=0

3x(4x-3)-4(4x-3)=0

(3x-4)(4x-3)=0

So, x = 4/3 , 3/4

Thus the number can be  x = 4/3 , 3/4
