Calculating percentages can sometimes feel like a daunting task, but it’s really just about breaking things down into simpler parts. So, let’s dive right in and figure out what 90% of 15 actually means.
To find a percentage of a number, you multiply the number by the percentage expressed as a decimal. In this case, we want to calculate 90% of 15. First, convert the percentage into decimal form:
90% = 0.9.
Now that we have our decimal, we simply multiply:
0.9 × 15 = 13.5.
So there you have it! Ninety percent of fifteen equals thirteen point five (or simply put, $13.50 if you're thinking in terms of money). This calculation isn’t just useful for math homework; understanding how to work with percentages comes in handy in everyday life—whether you're budgeting your expenses or figuring out discounts while shopping.
Next time someone asks you about percentages or when you encounter them yourself—like calculating tips at restaurants or determining interest rates—you’ll be equipped with this simple method to tackle those numbers confidently.
