Introduction

Multiplication is a fundamental operation in mathematics that is used to find the product of two or more numbers. In this article, we will focus on solving the multiplication problem 0.45 × 2.4. This problem may seem simple, but it requires attention to detail and a clear understanding of the multiplication process.

Understanding the Problem

Before we dive into the solution, let's break down the problem and understand what it's asking for. We are given two decimal numbers, 0.45 and 2.4, and we need to find their product. The product of two numbers is the result of multiplying them together.

Step 1: Multiply the Numbers

To solve the problem, we need to multiply 0.45 by 2.4. We can start by multiplying the numbers as if they were whole numbers, and then adjust the decimal places accordingly.

Multiply the Whole Numbers

First, let's multiply the whole numbers 45 and 24.

45 × 24 = 1080

Adjust the Decimal Places

Now, we need to adjust the decimal places to reflect the original numbers. We have 0.45, which has one decimal place, and 2.4, which has one decimal place as well. To adjust the decimal places, we need to multiply the result by 10 for each decimal place.

0.45 × 2.4 = (45 × 24) / (10^1 × 10^1) = 1080 / 100 = 10.80

Step 2: Check the Answer

Now that we have the result, let's check if it's correct. We can do this by multiplying the original numbers again and comparing the result with our answer.

0.45 × 2.4 = 1.08

Conclusion

In this article, we solved the multiplication problem 0.45 × 2.4 using a step-by-step approach. We broke down the problem, multiplied the numbers, adjusted the decimal places, and checked the answer to ensure it was correct. By following these steps, you can solve similar multiplication problems with ease.
