3.6: A Decimal Decoded

The number 3.6 is a decimal, a type of number that represents a part of a whole. But what does 3.6 really mean? Let's break it down.

What are decimals?

Decimals are a way of representing numbers that are not whole numbers. They use a decimal point (.) to separate the whole number part from the fractional part. The digits to the right of the decimal point represent fractions with denominators that are powers of ten.

Understanding 3.6:

In the case of 3.6, the "3" represents the whole number part. The ".6" represents the fractional part, which is equivalent to 6/10. Therefore, 3.6 is equivalent to 3 and 6/10.

Visualizing 3.6:

Imagine a pie divided into ten equal slices. If you have three whole pies and six slices from another pie, you have a total of 3.6 pies.

Real-world examples:

• Measuring height: Your height might be measured as 5 feet 3.6 inches.
• Shopping: A pack of gum might cost $3.60.

• Adding and subtracting: When adding or subtracting decimals, make sure to align the decimal points.
• Multiplying and dividing: When multiplying or dividing decimals, you need to consider the placement of the decimal point.
• Converting fractions to decimals: To convert a fraction to a decimal, divide the numerator by the denominator.

Key takeaways:

• Decimals are a useful way to represent numbers that are not whole numbers.
• The digits to the right of the decimal point represent fractions with denominators that are powers of ten.
• Decimals are used in a variety of calculations and real-world applications.

Further exploration:
