**Quick Answer for Whats 20 of 80 = 16**

**3 method to solve Whats 20% of 80 – With Formula**

Looking for how to solve the problem “What’s 20% of 80?” using various methods. Percentage calculations are essential in everyday life, from shopping discounts to financial investments.

**Method 1: Using the Percentage Formula**

The percentage formula is a fundamental approach to calculate percentages. It is given by:

**Percentage = (Part / Whole) * 100**

In our problem, we need to find 20% of 80, where 80 is the whole and 20 is the percentage we want to calculate.

**Step 1:** Convert the percentage to a decimal. To do this, divide the percentage by 100.

20% = 20/100 = 0.20

**Step 2:** Plug the values into the percentage formula:

Percentage = (0.20 * 80) = 16

**Therefore, 20% of 80 is 16.**

**Method 2: Using Proportions**

Proportions provide an alternative method to find percentages. In this approach, we set up a ratio between the known percentage and the unknown value.

**Step 1:** Set up a proportion:

20/100 = x/80

**Step 2:** Cross-multiply and solve for x:

20 * 80 = 100 * x

1600 = 100x

**Step 3:** Isolate x by dividing both sides by 100:

x = 1600/100

x = 16

**Thus, 20% of 80 is 16.**

**Method 3: Shortcut Approach**

For some common percentages, we can use shortcuts to find the result mentally.

Since 20% is equivalent to 1/5 (or 20/100 = 1/5), we can directly calculate it without using a calculator:

Step 1: Find 1/5 of 80:

(1/5) * 80 = 16

**Hence, 20% of 80 is 16.**

**Real-Life Example:**

Let’s say you’re shopping and come across a sale offering a 20% discount on a $80 shirt. Using the methods above, you can quickly determine that the discounted price would be $16 less, making the shirt cost only $64.

**Calculating percentages** is an essential skill, and there are various approaches to solve such problems. By using the percentage formula, proportions, or employing shortcuts, you can efficiently handle real-life situations involving percentages. Remembering these methods will not only assist you in everyday scenarios but also in more complex mathematical calculations.
