📘 Part 1: Worked Examples — Step by step

Visual model: Imagine a circle (pie) split into 2 equal parts; 1 part is shaded (one half).

Step 1 — Fraction to decimal: Divide numerator by denominator: 1 ÷ 2 = 0.5.

Step 2 — Decimal to percentage: Multiply the decimal by 100: 0.5 × 100 = 50%. So 1/2 = 0.5 = 50%.

Visual model: Picture a square split into 4 equal blocks; 3 blocks shaded (three quarters).

Step 1: 3 ÷ 4 = 0.75.

Step 2: 0.75 × 100 = 75%. So 3/4 = 0.75 = 75%.

Visual model: Imagine 5 equal blocks in a row; 2 blocks shaded.

Step 1: 2 ÷ 5 = 0.4.

Step 2: 0.4 × 100 = 40%. So 2/5 = 0.4 = 40%.

Tip: To convert a decimal to a percentage, multiply by 100. To convert a percentage to a decimal, divide by 100. To convert a decimal to a simple fraction, write as number over 100 then simplify if possible.

🎨 Part 3: Draw & Convert — Visual models

Draw a visual model (pie chart or blocks) for each fraction, then convert to decimal and percentage. Show your calculations.

Final reminder: For each conversion write the three forms clearly (fraction = decimal = percentage). Use your drawings to check your answers.
