Understanding how to convert decimals to fractions can feel like solving a mystery, but it’s a skill that comes in handy more often than you think. Let’s break it down step by step.

Understanding Decimals and Fractions

What Is a Decimal?
A decimal is a way of representing numbers that aren’t whole. It uses a point (.) to separate the whole part from the fractional part.

What Is a Fraction?
A fraction represents a part of a whole, written as two numbers separated by a slash, like 3/4. The top number is the numerator, and the bottom number is the denominator.

Why Convert?
Sometimes, decimals don’t tell the whole story—pun intended. Fractions are easier to use in specific contexts, like cooking or measuring.

The Basics of Converting Decimals to Fractions

Converting decimals to fractions is straightforward if you follow these steps:

1. Write the decimal as a fraction with 1 as the denominator (e.g., 0.7 = 0.7/1).
2. Multiply both numerator and denominator to eliminate the decimal.
3. Simplify the resulting fraction.
