Page 2: Worked Solutions and Answers

This page provides complete solutions to the percentage problems introduced on page 1, showing step-by-step calculations and final answers.

Example: Increasing £150 by 7%:

Convert to multiplier: 107% = 1.07
Calculate: 1.07 × 150 = 160.50

Highlight: The answers demonstrate how the multiplier method produces accurate results efficiently.

Definition: Percentage decrease calculations use multipliers less than 1, while increases use multipliers greater than 1.

The page includes complete solutions for all six problems, showing both the working process and final answers:

£150 increased by 7% = 160.50
£200 increased by 50% = 300
$4.80 increased by 1% = 484.80
5.72kg decreased by 2% = 560.56
80 decreased by 20% = 64
240 decreased by 0.5% = 238.80

Page 1: Introduction to Percentage Calculations

This page introduces the fundamental concepts of increasing and decreasing values using percentages and fractions. The content focuses on teaching the multiplier method for percentage calculations.

Definition: The multiplier method converts percentage changes into decimal numbers for easier calculation.

Example: To increase by 7%, add 100% + 7% = 107%, then convert to 1.07 as the multiplier.

Highlight: When decreasing values, subtract the percentage from 100% to find the correct multiplier.

Vocabulary: A multiplier is a decimal number used to calculate percentage changes in a single step.

The page demonstrates various calculations including increasing £150 by 7%, £200 by 50%, and $4.80 by 1%, as well as decreasing 5.72kg by 2%, 80 by 20%, and 240 by 0.5%.
