Study Notes
Ratio, Proportion, and Rate
- A ratio compares two quantities, written as a:b or a/b. Simplify by dividing by the greatest common factor.
- A proportion is an equation stating two ratios are equal, like a/b = c/d. Solve by cross-multiplying.
- A rate compares quantities with different units (e.g., speed = distance/time).
Reviewing Number Concepts
- Understand integers, fractions, decimals, and percentages. Learn to convert between these forms.
- Master the basic arithmetic operations (addition, subtraction, multiplication, and division) on these number types.
- Learn about factors, multiples, and prime numbers including prime factorization techniques.
- Find the least common multiple (LCM) and highest common factor (HCF).
- Develop skills in estimation and approximation by rounding numbers to significant figures or decimal places.
Making Sense of Algebra
- Combine like terms and simplify algebraic expressions.
- Solve algebraic equations using the balancing method.
- Represent inequalities on number lines.
- Substitute values for variables in algebraic expressions.
Fractions and Standard Form
- Simplify, compare, and calculate with fractions.
- Convert between improper fractions and mixed numbers.
- Express numbers in scientific notation, also known as standard form, as a × 10n where 1 ≤ a < 10.
