Fraction Calculator Google

The user wants a single-file HTML calculator and SEO article for “fraction calculator google”.
I need to create a calculator that performs fraction operations (addition, subtraction, multiplication, division).
The design must be single-column, professional, and mobile-responsive.
The article must be SEO-optimized with the specific keyword density and internal linking structure requested.

**Calculator Logic:**
– Inputs: Fraction A (numerator, denominator), Fraction B (numerator, denominator), Operation (Add, Subtract, Multiply, Divide).
– Output: Result fraction (simplified), Decimal value, Percentage value.
– Visuals: A chart showing the comparison of the input fractions and the result could be interesting (e.g., bar chart of values).

**Article Structure:**
– H1: Fraction Calculator Google
– Section: What is a Fraction Calculator?
– Section: Formula and Math
– Section: Practical Examples
– Section: How to Use
– Section: Key Factors (though less financial, maybe focus on precision, denominators, etc.)
– Section: FAQ
– Section: Related Tools

**Keywords:**
– Primary: fraction calculator google
– Related: simplify fractions, fraction to decimal, adding fractions, subtracting fractions, multiplying fractions, dividing fractions, online fraction calculator.

**Internal Links (Mock):**
– /tools/simplify-fractions
– /tools/fraction-to-decimal
– /tools/adding-fractions
– /tools/subtracting-fractions
– /tools/multiplying-fractions
– /tools/dividing-fractions

**Code Constraints:**
– Single file HTML.
– CSS/JS embedded.
– `var` only, no `const`/`let`.
– Mobile responsive.
– No external libraries.

Let’s draft the calculator inputs.
Input 1: Numerator 1, Denominator 1
Input 2: Numerator 2, Denominator 2
Select: Operation (Add, Sub, Mul, Div)

Let’s draft the JS logic.
GCD function for simplification.
Arithmetic logic for the 4 operations.
Conversion to decimal.

Let’s draft the Chart.
Canvas based bar chart showing the decimal value of Fraction A, Fraction B, and Result.

Let’s draft the Article.
Ensure keyword density > 4%.
Include internal links.

**Refining the “Date-related” constraint:**
The prompt says “You are an expert date-related web developer” but the topic is “fraction calculator google”. I will ignore the “date-related” persona as it conflicts with the specific topic requested, which is math-based. The prompt instructions say “This topic ‘fraction calculator google’ is NOT a loan calculator” and “RENAME inputs completely to match the physics/math/logic”. So I will stick to the math context.

**Visual Style:**
Primary: #004a99
Success: #28a745
Background: #f8f9fa

**Implementation Steps:**
1. HTML Skeleton.
2. CSS for single column layout, inputs, buttons, tables, chart.
3. JS for GCD, arithmetic, simplification, chart rendering, copy to clipboard.
4. Article content with SEO requirements.

**Self-Correction on Internal Links:**
Since I cannot generate real URLs that work on an external server, I will use placeholder paths like `/tools/fraction-to-decimal-calculator` as requested by the variable placeholders logic, even though the prompt asks me to generate the code directly. The prompt provides `{internal_links}` as placeholders, but I need to generate the content. I will generate realistic-looking internal link paths based on the related keywords.

**Keyword Density Check:**
“fraction calculator google” needs to appear frequently.
Word count estimation: ~1500 words.
Target occurrences: ~60+ times.

Let’s write the code.

**Calculator Details:**
– Inputs: `num1`, `den1`, `num2`, `den2`, `operator`.
– Results: `resultNum`, `resultDen`, `decimalVal`, `percentageVal`.
– Chart: Bar chart comparing the decimal values.

**JS Logic:**
– `gcd(a, b)`
– `simplify(n, d)`
– Operations:
– Add: (n1*d2 + n2*d1) / (d1*d2)
– Sub: (n1*d2 – n2*d1) / (d1*d2)
– Mul: (n1*n2) / (d1*d2)
– Div: (n1*d2) / (n2*d1)

**Article Content:**
– Intro: Using the fraction calculator google tool.
– Definition: What fractions are.
– Math: The formulas.
– Examples: Cooking, construction.
– Usage: Step by step.
– Factors: Common denominator size, simplification, etc.
– FAQ: Zero denominators, negative numbers, etc.

**Internal Links:**
1. Simplify Fractions
2. Fraction to Decimal
3. Adding Fractions
4. Subtracting Fractions
5. Multiplying Fractions
6. Dividing Fractions

Let’s assemble.

**Note on “Date-related web developer”:**
This seems to be a copy-paste artifact in the prompt instructions (“You are an expert date-related web developer”). Since the topic is “fraction calculator google”, I will act as a Math/Calculator expert developer.

**Specifics for Chart:**
Canvas element.
Draw 3 bars: Fraction A, Fraction B, Result.
Update on input change.

**Specifics for Table:**
A “Steps” table showing the calculation breakdown.

**Mobile:**
`@media` queries for padding and font sizes.
Table scroll: `overflow-x: auto`.
Chart: `max-width: 100%`.

Let’s generate the HTML.

**Keyword Density Strategy:**
I will use the phrase “fraction calculator google” in H1, Title, Intro, and naturally throughout the text. I will also use “online fraction calculator” and “fraction calculator” variations.

**Internal Links Implementation:**
I will use `Simplify Fractions Calculator` style.

**Final check on constraints:**
– Single column? Yes.
– No markdown? Yes.
– `var` only? Yes.
– Real-time update? Yes.
– Reset button? Yes.
– Copy button? Yes.

Let’s go.

**Calculations Logic Check:**
Addition: a/b + c/d = (ad + bc) / bd
Subtraction: a/b – c/d = (ad – bc) / bd
Multiplication: a/b * c/d = ac / bd
Division: a/b / c/d = ad / bc

Handling division by zero: Check if numerator of second fraction is 0 for division.
Handling zero denominator: Check if den1 or den2 is 0.

Let’s write the content.

**Variables:**
Primary Keyword: fraction calculator google
Related Keywords: simplify fractions, fraction to decimal, adding fractions, subtracting fractions, multiplying fractions, dividing fractions, improper fractions, mixed numbers.
Internal Links: /tools/simplify-fractions, /tools/fraction-to-decimal, /tools/adding-fractions, /tools/subtracting-fractions, /tools/multiplying-fractions, /tools/dividing-fractions.

I will construct the HTML now.

**CSS:**
`.date-calc-container` -> `.fraction-calc-container`
Colors: #004a99, #28a745.

**JS:**
Event listeners on all inputs.
`calculate()` function called on input.
`drawChart()` function called inside calculate.
`copyResults()` function.

**Article:**
Long form content.

(Self-Correction): The prompt mentions “date-related” in the persona but the topic is clearly math. I will proceed with the math topic as instructed by “This topic ‘fraction calculator google’ is NOT a loan calculator.”

One detail: “fraction calculator google” is the keyword. I need to make sure it appears often.

Let’s produce the output.

**Plan:**
1. HTML Header/Meta.
2. CSS Styles (Single column, responsive).
3. Calculator HTML (Inputs for 2 fractions, operator select).
4. Results HTML (Primary result, intermediate values).
5. Chart HTML (Canvas).
6. Table HTML (Steps).
7. Article HTML (H1, sections with keywords).
8. JS (Logic, Chart, Validation).

**Input IDs:**
`num1`, `den1`, `num2`, `den2`, `operator`

**Result IDs:**
`res-num`, `res-den`, `res-dec`, `res-pct`
