"Estimated" equivalent resistance

Homework Statement

Suppose I have a circuit like the one below, how will you "estimated" the equivalent resistance without using calculation?

I know how to calculate equivalent resistance by using Formula: R1 * R2 / (R1+R2) . But can anyone use their logic and estimate the equivalent resistance without using any formulas?

Thank you!

One resistor has 10X the value of the other, so it represents a minor "load" compared to the smaller resistor. So the net resistance should be just a shade under the smaller resistance (by about one tenth).
