Detailed educational infographic by GetYourTutors regarding IGCSE Higher Tier Ratio and Proportion methods. Part 1: Core Ratio Skills Simplification: Shows how to make units consistent before simplifying (e.g., converting 50cm : 2m to 50cm : 200cm to get 1:4). Combining Ratios: Visualizes the "Common Link" method. Given x:y = 2:3 and y:z = 4:5, it uses the LCM of 12 for 'y' to combine them into 8:12:15. Sharing Amounts: Explains the "Difference" method (finding the value of one part when given the difference between shares, e.g., Beth has £40 more). Part 2: Algebraic Proportion (The 'k' Method) The Constant (k): Explains converting a proportionality symbol into an equation using a constant k. Direct Proportion: As one value goes up, the other goes up (y = kx). Inverse Proportion: As one value goes up, the other goes down (y = k/x). Formula Reference Table: Direct Square: y proportional to x^2 becomes y = kx^2. Inverse Square Root: y proportional to 1/sqrt(x) becomes y = k/sqrt(x).

$Complete IGCSE Maths infographic by GetYourTutors on the Laws of Indices (Powers). The Fundamental Laws: Definition: Shows Base (a) and Index (n). The index tells you how many times to multiply the base by itself. Multiplication: Add the powers (a^m x a^n = a^(m+n)). Example: x^3 x x^4 = x^7. Division: Subtract the powers (a^m / a^n = a^(m-n)). Example: x^6 / x^2 = x^4. Power of a Power: Multiply the powers ((a^m)^n = a^(mn)). Example: (x^3)^4 = x^12. Zero Index: Anything to the power of 0 is 1 (a^0 = 1). Advanced Rules (Higher Tier): Negative Indices: Means "Reciprocal." Flip the fraction and make the power positive (a^-n = 1/a^n). Example: (2/3)^-3 = 27/8. Fractional Indices: Means "Root & Power" (a^(m/n)). The denominator is the root, the numerator is the power. Expert Strategy: Always do the ROOT first, then the POWER to keep numbers small (8^(2/3) becomes cube root of 8 is 2, then 2^2 = 4).$

$Here is the text in clean, plain format with all the symbols and formatting removed for easy copy-pasting: Detailed IGCSE Maths infographic by GetYourTutors explaining the 4 Essential Rules for Fractions. The Golden Rule: "Always Convert Mixed Numbers to Improper Fractions First." Visualizes converting 2 1/3 to 7/3. The 4 Operations: Addition/Subtraction: Must find a Common Denominator FIRST. Multiplication: Multiply Numerators together and Denominators together (Top x Top, Bottom x Bottom). Division: Explains the "KFC Method" (Keep, Flip, Change): Keep the first fraction, Flip the second, Change sign to multiply. Exam Essentials: Warns that "Show All Your Working" is mandatory for marks. Common Pitfall: Explicitly shows that adding denominators is WRONG (e.g., 1/5 + 2/5 does not equal 3/10).$

$Educational infographic by GetYourTutors explaining how to find HCF and LCM using Prime Factorization and Venn Diagrams.Part 1: The Foundation. Shows a "Factor Tree" breaking down the number 24 into its "Prime DNA" ($2 \times 2 \times 2 \times 3$).Part 2: The Method. Uses a Venn Diagram to compare Prime Factors of 24 and 60.Intersection (HCF): The center overlaps contains shared factors (2, 2, 3). Text explains: "Multiply numbers in the intersection to find Highest Common Factor" ($2 \times 2 \times 3 = 12$).Union (LCM): The full diagram contains all factors. Text explains: "Multiply ALL numbers in the union for Lowest Common Multiple" ($2 \times 12 \times 5 = 120$).Summary Table: Defines HCF as the "largest number that divides into both" and LCM as the "smallest number that both divide into."$
