What Is 8 Divided By 48

What is 8 Divided by 48? A Deep Dive into Division and its Applications

The seemingly simple question, "What is 8 divided by 48?", opens a door to a fascinating exploration of division, its practical applications, and the broader world of mathematics. While the answer itself is straightforward, understanding the process and its implications offers valuable insights into various fields. This article will not only provide the solution but will also delve into the intricacies of division, explore different methods of calculation, and showcase its relevance in real-world scenarios.

Understanding Division: The Basics

Division is one of the four fundamental arithmetic operations, alongside addition, subtraction, and multiplication. It represents the process of splitting a quantity into equal parts or groups. In the equation 8 ÷ 48, we are asking: "How many times does 48 fit into 8?" Or, equivalently, "If we divide 8 into 48 equal parts, how large is each part?"

Key Terminology:

• Dividend: The number being divided (in this case, 8).
• Divisor: The number by which we are dividing (in this case, 48).
• Quotient: The result of the division (the answer we are seeking).
• Remainder: The amount left over after the division if the dividend is not perfectly divisible by the divisor.

Calculating 8 Divided by 48: Methods and Solutions

The most straightforward way to calculate 8 ÷ 48 is through long division or by converting the division into a fraction.

Method 1: Long Division

While long division might seem daunting for this particular problem, it provides a structured approach applicable to more complex divisions. Let's break down the steps:

1. Set up: Write the dividend (8) inside the division symbol and the divisor (48) outside.

   48 | 8
   

2. Compare: Since 8 is smaller than 48, we know the quotient will be less than 1. We can add a decimal point and a zero to the dividend to continue the division.

   48 | 8.0
   

3. Divide: How many times does 48 go into 80? It goes in once (48 x 1 = 48). Write 0.1 above the 8.

   0.1
   48 | 8.0
   

4. Subtract: Subtract 48 from 80: 80 - 48 = 32.

   0.1
   48 | 8.0
   -48
   ---
   32
   

5. Bring down: Bring down the next digit (another zero).

   0.1
   48 | 8.00
   -48
   ---
   320
   

6. Repeat: How many times does 48 go into 320? It goes in 6 times (48 x 6 = 288). Write 6 after the decimal point.

   0.16
   48 | 8.00
   -48
   ---
   320
   -288
   ---
   32
   

7. Continue: We can continue this process adding more zeros and repeating the steps, but we will see that the decimal will continue infinitely, giving us a repeating decimal.

Therefore, 8 divided by 48 is approximately 0.166666... or 0.1667 (rounded to four decimal places).

Method 2: Fraction Conversion

We can express the division as a fraction: 8/48. This fraction can be simplified by finding the greatest common divisor (GCD) of 8 and 48. The GCD of 8 and 48 is 8. Dividing both the numerator and the denominator by 8, we get:

8 ÷ 8 = 1 48 ÷ 8 = 6

Therefore, 8/48 simplifies to 1/6.

To convert the fraction 1/6 to a decimal, we perform the long division 1 ÷ 6, which also yields the repeating decimal 0.166666...

Practical Applications of Division: Real-World Examples

Division is not just a mathematical concept; it's a fundamental tool used in countless everyday situations and various professional fields.

Everyday Life:

• Sharing: Dividing a pizza among friends.
• Measurement: Converting units (e.g., converting inches to feet).
• Cooking: Dividing ingredients according to a recipe.
