Basic Concepts

Fractions, Decimals, and Conversions

Understanding Fractions and Decimals

Many SAT questions use fractions and decimals, and calculators can quickly convert between them. Some calculators have a dedicated fraction key or can convert decimals to fractions and vice versa.

Accurate Conversions

  • Use the fraction key (often labeled as \( \frac{a}{b} \) or \( \boxed{ab/c} \)) to enter and simplify fractions.
  • Use the \( \rightarrow \) (convert) key to switch between decimals and fractions.

Why It Matters

Some SAT answers must be given in a specific format, so knowing how to convert and simplify is key.

Everyday Use

Fractions and decimals come up in everything from recipes to budgeting!

Examples

  • Converting 0.75 to \( \frac{3}{4} \) using the fraction conversion function.

  • Adding \( \frac{1}{3} + 0.25 \) by converting both to decimals before adding.

In a Nutshell

Learn to quickly convert and simplify fractions and decimals using your calculator.
