If 80 is reduced by `15%`, find the decreased amount.

Answer

To find the decreased amount when 80 is reduced by 15%, follow these steps:

### Step 1: Calculate 15% of 80
To find the decreased amount, we first need to calculate 15% of 80. The formula for calculating percentage is:

\[ \text{Percentage} = \frac{\text{Percentage Rate}}{100} \times \text{Total Amount} \]

So, we calculate:

\[ 15\% \text{ of } 80 = \frac{15}{100} \times 80 \]

### Step 2: Simplify the calculation
Now, simplify the calculation:

\[ 15\% \text{ of } 80 = \frac{15 \times 80}{100} = \frac{1200}{100} = 12 \]

### Step 3: Find the decreased amount
Now that we have calculated 15% of 80, which is 12, we can find the decreased amount by subtracting this value from the original amount:

\[ \text{Decreased Amount} = 80 - 12 = 68 \]

### Final Answer
Thus, the decreased amount when 80 is reduced by 15% is **68**.
