"if the inclination of Earth and Venus orbit was the same, how often would the transit occur?"

I am given 4 options and I have got the right answer, but I did it by trial and error, and I am sure that there must be a better solution.

I looked up Venus's Orbital Period and it's 224.7 days. Call it 224 days.

So if we start off in a transit with the planets aligned on an axis, the two planets trace out different angular displacements over time:

Earth 2Pi/365 days and Venus 2Pi/365 days. I thought that I should be able to create a simple equation and solve, but I can't. Can anyone help?

I worked out by putting days in that the answer is 581 days (maybe small error due to rounding), but I am more interested in how I should go about solving this.

Please note that I am a pre-University student so go easy on me! Thanks
