Question
An electronic circuit has two 13-k? resistors, R1 andR2, connected in series as shown in (Figure 1) . The battery voltage is 6.0V and it has negligible internal resistance. A voltmeter is connected across R1, as shown in (Figure 2) .
What internal resistance should the voltmeter have to be in error by less than 5{ m %} ?

Just use V=R.I, calculate how much current the circuit have. Later, See what is the value of which resistor, see how much voltage falls in each resistor, then, when you know this, apply V=I.R in this resistor, so that would be the internal resistor or it's call impedance.
