Calculate 30% of 40: Direct Percentage Multiplication

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information
• Step 2: Apply the percentage formula
• Step 3: Perform the necessary calculation

Now, let's work through each step:
Step 1: The problem asks us to find 30% of 40.
Step 2: We'll use the percentage formula: $\text{Percentage value} = \frac{\text{Percentage}}{100} \times \text{Quantity}$.
Step 3: Replacing the variables with the given values, we have: $\text{Percentage value} = \frac{30}{100} \times 40$.
To simplify, multiply $\frac{30}{100} \times 40$:
First, convert 30% to a decimal fraction, which is $\frac{30}{100}$ or $0.3$.
Then multiply 0.3 by 40:
$0.3 \times 40 = 12$.

Therefore, the solution to the problem is 12.
