Finding 20% of $17 is a straightforward calculation with a couple of approaches. This article will break down how to solve this problem, showing you the steps and explaining the underlying math. Whether you're tackling a percentage problem for school, work, or just everyday life, understanding the method is key. This simple percentage calculation is a fundamental skill applicable to many situations.

Method 1: Converting the Percentage to a Decimal

The most common method involves converting the percentage to its decimal equivalent. Remember that percentages represent parts of 100. To convert 20% to a decimal, divide it by 100:

So, finding 20% of $17 is the same as finding 1/5 of $17:

$17 / 5 = $3.40

Again, we arrive at the answer: 20% of $17 is $\boxed{3.40}.

Understanding how to calculate percentages is a crucial life skill. Whether you're calculating tips, discounts, sales tax, or understanding interest rates, percentage calculations are used everywhere. Mastering this skill will significantly improve your numeracy and help you confidently tackle various real-world problems.

This seemingly simple calculation has broader implications in understanding financial concepts and making informed decisions. From budgeting to investment, percentages play a critical role. Knowing how to calculate them quickly and accurately is an invaluable asset.
