What is the largest positive multiple of $12$ that is less than $350?$
I want to find the largest positive multiple of $12$ that is less than $350$, so I need to divide $350$ by $12$ and round down to the nearest integer. Dividing $350$ by $12$ gives me $29.1666\ldots$, so the nearest integer that is less than that is $29$. Therefore, the largest positive multiple of $12$ that is less than $350$ is $29$ times $12$, which is $348$.
