Answer: 67.8%

Step by step solution

01

Identify the part and the whole

The part is the number of electoral votes won by Obama, which is 365. The whole is the total number of electoral votes, which is 538.
02

Apply the percentage formula

The formula to find the percentage is (part/whole) * 100. In this case, the part is 365 and the whole is 538. So the formula becomes: Percentage = (365/538) * 100
03

Calculate the percentage

Now we just need to plug the values into the formula: Percentage = (365/538) * 100 = 0.678437 * 100
04

Round to the nearest tenth of a percent

Multiply the result by 100 to get the percentage: Percentage = 67.8437 To round to the nearest tenth of a percent, we look at the hundredths place. Since it's a 4 (less than 5), we round down: Percentage 鈮� 67.8% So, Barack Obama won approximately 67.8% of the total electoral votes in the 2008 presidential election.
