Solve Decimal Multiplication: 0.4 × 115

To solve this problem, we need to calculate the product of $0.4$ and $115$.

First, let's perform the multiplication:

Multiply $115$ by $0.4$:

$115 \times 0.4 = 46$

Here's how the calculation works step-by-step:

• Consider $0.4$ as $\frac{4}{10}$.
• Therefore, the multiplication becomes $115 \times \frac{4}{10}$.
• Perform the multiplication first: $115 \times 4 = 460$.
• Then divide by $10$ to manage the decimal place:$\frac{460}{10} = 46$.

Thus, the solution to the problem is $46$.
