Answer 1

At least 67 votes

Step-by-step explanation:

We were given the following information:

There are 100 senators in the US senate,

At least 2/3 of them vote yes in order to ratify or approve, a treaty

The least number of votes needed is calculated below:

`\begin{gathered} x\ge(2)/(3)(100) \\ \text{Expand the bracket, we have:} \\ x\ge66.6667 \\ x\ge67 \\ \\ \therefore x\ge67 \end{gathered}`

Therefore, they must have at least 67 votes to ratify a treaty
