The ratio of Republican voters to Democrat voters can be simplified by dividing both percentages by 15, which gives a ratio of 3:2 or 1.5:1. This means that for every 3 voters who plan on voting for the Republican candidate, there are 2 voters who plan on voting for the Democrat candidate. Therefore, choice B is the best answer. To determine the ratio of Republican voters to Democrat voters, we need to compare the number of voters who plan on voting Republican to the number who plan on voting Democrat. We can simplify this ratio by dividing both sides by the smaller number to get the ratio in the form of some quantity to 1. Dividing both sides by 30, we get:

Republicans:Democrats = 45/30 : 30/30 = 3/2 : 1

So the ratio of Republican voters to Democrat voters is 3:2 or 1.5:1. The correct choice is B.
