Question 1108396: Kindly help please. The total voltage of first circuit is (9 + 3i) volts. The total voltage of a second circuit is (5 - 2i) volts. We need to find the ratio of the total voltage of the first circuit to that of the second circuit. Does it mean, we're going to divide? After I divided the 2 voltages (I used the conjugate of the second voltage), I got (39 + 33i) / 29. Is that the ratio already? Or should it be like in the form "first circuit is to second circuit"? Thank you.

The problem asks for the ratio  %289%2B3i%29%2F%285-2i%29.

That is the ratio.
You are starting with +V%5B1%5D%2FV%5B2%5D+ which is the ratio. The fact you multiply the top and bottom by the conjugate just changes the form.
