Understanding Fractions and Decimals

Before we begin the conversion process, it's essential to grasp what fractions and decimals represent.

What is a Fraction? 🍰

A fraction consists of two parts: the numerator (the top part) and the denominator (the bottom part). In our case, 39 is the numerator and 80 is the denominator. This fraction represents a division problem: how many parts of 80 do we have, given that we possess 39 parts.

What is a Decimal? 💡

Decimals are another way to express fractions, where numbers are separated by a decimal point. For example, the decimal representation of 0.5 corresponds to the fraction 1/2.

Why Convert Fractions to Decimals? 🤔

Converting fractions to decimals can simplify calculations, especially when performing operations like addition, subtraction, multiplication, and division. Decimals are often easier to work with in real-life applications, such as financial transactions.

Steps to Convert 39/80 to Decimal

Now that we have a foundational understanding, let's move on to the steps needed to convert the fraction 39/80 into a decimal.

Step 1: Division 📊

To convert the fraction 39/80 into a decimal, you simply need to divide the numerator by the denominator:

[ 39 \div 80 ]

Step 2: Performing the Division

1. Set up the division: You can perform this division manually or use a calculator.
2. Manual Calculation: If calculating manually, you’ll begin dividing 39 by 80. Since 39 is less than 80, you’ll need to add a decimal point and a zero to the numerator (making it 390).
3. Continue the Division:
   • 80 goes into 390 four times (because (80 \times 4 = 320)).
   • Subtract 320 from 390 to get 70.
   • Bring down another zero, making it 700.
   • 80 goes into 700 eight times (because (80 \times 8 = 640)).
   • Subtract 640 from 700 to get 60.
   • Bring down another zero, making it 600.
   • 80 goes into 600 seven times (because (80 \times 7 = 560)).
   • Subtract 560 from 600 to get 40.
   • Bring down another zero, making it 400.
   • 80 goes into 400 five times (because (80 \times 5 = 400)).
   • Finally, subtract to get zero.

Conclusion of Calculation

Through this method, we discover that:

[ 39/80 = 0.4875 ]

Therefore, the decimal representation of 39/80 is 0.4875. ✅
