Question

If two resistors with respective resistance R1 and R2 are hooked up in parallel, the net resistance R is related to R1 and R2 by 1/R = 1/R1 + 1/R2. If the resistances are measured in ohms as R1 = 150Ω, R2 = 400Ω, both with a possible error of 10%, what is the net resistance and the maximum possible error in the calculated value of R?
