In the diagram, R1 = 40.0 ohm, R2 = 25.4 ohm, and R3 = 70.8 ohm. What is the equivalent resistance of the group?​

The resistors are in series connection, so the equivalent resistance of will be their sum.

Now, the equivalent resistance of and is the total resistance of the circuit, and since they are in parallel connection, Total resistance :
