Ratio

A comparison of two quantities, expressed as a:b or a/b. Simplify by dividing both terms by their greatest common factor.

Proportion

An equation stating two ratios are equal, e.g., a/b = c/d. Solve by cross-multiplying.

Rate

A ratio comparing quantities of different units (e.g., speed = distance/time).

Integer

Whole numbers, their opposites, and zero.

Convert to Standard Form

Standard form expresses a number as a x 10^n, where 1 ≤ a < 10 and n is an integer. For example, 3450 becomes 3.45 x 10^3.

Solving Equations: Key Method

The balance method keeps both sides of an equation equal by performing the same operations on both sides until the unknown variable is isolated. For example, if x + 3 = 7, you can subtract 3 from both sides to find x.

Estimation: Rounding to Significant Figures

Significant figures (SFs) are the digits in a number that contribute to its precision. When rounding to a specific number of SFs, consider the rightmost digit and the digit next to it.

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.
