Cooking and Recipe Maths: Scaling, Ratios and Fractions
Kitchen-based problems that make ratios and fractions delicious.
Works on any free AI · Best tool: Any AI chat (ChatGPT/Gemini/Claude/Copilot)
✅ How to use this effectively
- 1. Type the topic and class.
- 2. Name a familiar dish if you like.
- 3. Send and read the recipe problems.
- 4. Request a doubling/halving set.
- 5. Use the answer key to mark.
🔧 If it is not right, reply with this: If a scaled quantity looks wrong, reply: 'Re-scale every ingredient using the exact ratio and verify each amount a second way.'
THE PROMPT
ROLE: Act as a maths teacher who teaches ratios and fractions through cooking.
CONTEXT: My students are in [CLASS/GRADE] under [BOARD or EXAM]. Cooking is familiar to them at home. I want to teach [TOPIC e.g. ratio and proportion / fractions / unitary method] using real recipes (chai, dal, biryani, cake, sweets).
YOUR TASK:
1. Give one realistic base recipe for [DISH or let AI choose a common Indian dish] that serves a stated number of people, with ingredient quantities.
2. Create 8 problems: scale up to a party, scale down for one person, convert units (grams, cups, spoons, litres), keep a flavour ratio constant, cost the recipe, find how much of one ingredient is left.
3. Easy to hard.
4. Full solution for each.
INPUT: Here is the topic and dish (if any): [PASTE HERE].
HOW TO WORK IT OUT: Solve internally first. VERIFY each scaled quantity by two independent checks (multiply by the scale factor, then re-derive using the unitary method). Keep ingredient ratios consistent; never invent impossible amounts. Round sensibly to kitchen-friendly numbers and say when you have rounded. All maths legible.
OUTPUT FORMAT:
- 'Base Recipe' (table of ingredients and servings).
- 'Kitchen Problems' numbered 1 to 8 with marks.
- 'Solutions' (full working, each ending with 'Check:').
- 'Why It Matters' (2 lines on ratios in real cooking).
FORMAT THE OUTPUT — PRIMARY DELIVERABLE:
Return one complete, editable document ready to paste into Word or Google Docs. Use a descriptive title, short section headings, readable paragraphs, numbered actions and tables only where they make the material easier to use. Include every requested section; do not return formatting advice instead of the document.
MATHS FORMATTING: Write ALL mathematics so it reads correctly in a normal chat and pastes cleanly into Word or Google Docs. Use plain readable notation - for example a/b for fractions, x^2 for powers, sqrt(x) for roots, and symbols like <=, >=, !=, +-, pi, theta, integral and sum. Do NOT output raw LaTeX or code such as \frac{}{}, \sqrt{}, x^{2}, $...$ or \( ... \) - these appear as broken symbols to a teacher in a free chat.
RULES: Realistic quantities, simple language, nothing above class level.
CONTEXT CHECK: Before you begin, if any [SQUARE-BRACKET] above is still empty, or I have not given you the question / photo / data you need, ask me for exactly those and wait - never guess, and never answer with the placeholder text still in brackets.
GROUND RULES (always follow): Do not invent statistics, percentages, marks distributions you were not given, exam cut-offs, solve-time figures, NCERT or textbook page/line numbers, citations, or historical exam data. If you are unsure of any fact or number, say so and clearly label it an estimate; keep established fact separate from your own inference. Every step must be mathematically correct and at the stated class/board/exam level.
