## Calculating 0.4 x 20%

To calculate 0.4 x 20%, we need to understand that **"percent" means "out of one hundred."** Therefore, 20% is equivalent to 20/100.

Now, we can rewrite the problem as:

**0.4 x (20/100)**

**Step 1: Simplify the fraction.** 20/100 can be simplified to 1/5.

**Step 2: Multiply 0.4 by 1/5.**

0.4 x (1/5) = **0.08**

Therefore, **0.4 x 20% equals 0.08**.

## Understanding the Result

The result, 0.08, represents 8% of 0.4. It can be helpful to visualize this as a part of a whole. Imagine a bar representing 0.4, and we are trying to find 20% of that bar. The result, 0.08, represents a smaller section of the bar, which is 8% of the whole.

This calculation can be used in various scenarios, such as calculating discounts, calculating percentages of a quantity, or understanding proportions in different contexts.
