What Does 30 Percent Mean?

To understand what’s 30 percent of 200, we first need to grasp what the term "percent" means. The word "percent" comes from the Latin phrase "per centum," which translates to "by the hundred."

Part = (Percentage × Whole) / 100

Now, let’s plug in the values:

Part = (30 × 200) / 100
