Rational and Non-Rational Numbers

What students will learn

• Define rational numbers and non-rational (irrational) numbers with clear examples.
• Convert recurring decimals and terminating decimals into standard fraction forms (a/b where b ≠ 0).
• Identify non-rational numbers such as surds (e.g., √2, √3, √5) and special mathematical constants like π.
• Distinguish accurately between rational and non-rational numbers from a given set of real numbers.
• Classify square roots of perfect squares versus non-perfect squares correctly in preparation for BECE questions.
