Unpacking the Mystery: 1.5 Divided by 3

You might be surprised to find that a seemingly simple division problem like 1.5 divided by 3 can spark interesting discussions and lead to a deeper understanding of math. Let's delve into this problem and explore the different ways to solve it.

Understanding the Question

At its core, the question "1.5 divided by 3" asks: "How many times does 3 go into 1.5?". This can be represented mathematically as:

1.5 ÷ 3 = ?

Methods to Solve

There are multiple ways to solve this problem:

Long Division: This traditional method allows you to systematically divide 1.5 by 3. Here's a visual breakdown:
```
    0.5
   ----
3 | 1.5
    1.5
    ----
     0.0
```
We find that 3 goes into 1.5 0.5 times.
Decimal Division: We can simplify the division by treating it as dividing 15 by 30, and then adjusting the decimal place:
```
15 ÷ 30 = 0.5
```
Moving the decimal one place to the left gives us 0.5 as the final answer.
Fraction Conversion: Convert 1.5 to a fraction (3/2) and then divide by 3/1:
```
(3/2) ÷ (3/1) = (3/2) * (1/3) = 1/2 = 0.5
```

Why is the answer 0.5?

The answer 0.5 makes intuitive sense when we visualize the problem:

Imagine a cake cut into three equal slices. You have 1.5 slices (one and a half).
Each full slice represents 1/3 of the whole cake.
You have one full slice (1/3) plus half a slice (1/6).
Combining these, you have (1/3) + (1/6) = (2/6) + (1/6) = 3/6 = 1/2.

Applications

Understanding how to divide decimals is essential for many real-world applications:

Financial Calculations: Dividing expenses by the number of people to calculate individual contributions.
Measurement Conversions: Converting measurements between different units (e.g., kilometers to miles).
Engineering and Design: Calculating proportions and ratios in various projects.

Conclusion

While 1.5 divided by 3 may seem like a straightforward problem, it provides a solid foundation for grasping decimal division and its numerous applications. By understanding the different methods and their logic, you can confidently tackle similar problems and gain a deeper appreciation for the intricacies of math.
