Advanced Topics

Decimals and Their Relationship to Fractions

Connecting Fractions and Decimals

Decimals are another way to show parts of a whole, just like fractions. The tenths place comes right after the decimal point, then the hundredths.

Converting Fractions to Decimals

To change \( \frac{1}{2} \) into a decimal, divide 1 by 2 to get 0.5.

Comparing Decimals

Line up the decimal points and compare digits from left to right.

Real-Life Connection

Decimals are everywhere: money, measurements, and scores!

Key Formula

\[0.5 = \frac{1}{2}\]

Examples

  • 0.25 is the same as \( \frac{1}{4} \)

  • Which is greater: 0.3 or 0.28? (Answer: 0.3)

In a Nutshell

Decimals and fractions are two ways to show the same amount.

Key Terms

Decimal
A number that uses a point to show parts less than one.
Equivalent
Equal in value but written differently.
