How to find r1 and r2 values if only vout and vin is given. i have tried all voltage divider formulas but none of them work. I think it cant be found.
Yes, they do.i have tried all voltage divider formulas but none of them work.
If the circuit does not have to deliver any significant current (for example, it is driving only a volt meter), then there are an infinite number of resistor value combinations that will do what you want. If you stick to only resistor values you can buy, then there are approximately 331,000 1% tolerance resistor combinations.

This is probably the direction the original assignment was directed at. Give the required ratio of R1/R2 or an equation for R1=f(R2) (or vice versa).Chose a resistor (any value) for R1 and then R2 will be double this.

Not only ????? ?
