Question

To override a presidential veto, at least

66 2/3% of the Senate must vote to override the veto. There are 100 senators in the Senate. What is the minimum number of votes needed to override a veto?

Answer 1

To answer this question, you need to round to the nearest whole number, because you cannot have two thirds of a senator vote.  Since two thirds rounds up to 1, your answer would be 66 + 1, which is 67.  Therefore, the minimum number of votes to override a veto is 67 votes.

Answer 2

67 people need to vote

even though 2/3 is 66.66, it need to be rounded up to 67
