Calculating Voltage across Resistors R1, R2, R3, R4 in a 10V DC Circuit & Voltage for 28 Ohm R5

If I have a DC circuit with a 10 volt supply followed by a 10 ohm resistor (R1), leading to a 27 ohm resistor (R2), with an 18 ohm resistor (R3) and a 10 ohm resistor (R4) running in parallel alongside it.

What is the voltage running across each resistor in the circuit?

Please indicate the voltage running across R1, R2, R3 and R4.

Then indicate what the voltage would be for a resistor (R5), if it replaced the resistors in series (R3 and R4) and had a rating of 28 ohms.

Is this a school project?
