Understanding Fractions

Before using the calculator, it helps to understand fraction terminology.

A fraction consists of:$$\frac{Numerator}{Denominator}$$DenominatorNumerator​

Example:$$\frac{3}{4}$$43​

Where:

• 3 = Numerator
• 4 = Denominator

The denominator cannot be zero because division by zero is undefined.

---

Fraction Addition Formula

To add three fractions:$$\frac{a}{b} + \frac{c}{d} + \frac{e}{f}$$ba​+dc​+fe​

A common denominator is required.

The resulting numerator becomes:$$(a \times d \times f) + (c \times b \times f) + (e \times b \times d)$$(a×d×f)+(c×b×f)+(e×b×d)

The denominator becomes:$$b \times d \times f$$b×d×f

The final fraction is then simplified.

---

Fraction Subtraction Formula

To subtract three fractions:$$\frac{a}{b} - \frac{c}{d} - \frac{e}{f}$$ba​−dc​−fe​

The numerator becomes:$$(a \times d \times f) - (c \times b \times f) - (e \times b \times d)$$(a×d×f)−(c×b×f)−(e×b×d)

The denominator remains:$$b \times d \times f$$b×d×f

The answer is simplified afterward.

---

Fraction Multiplication Formula

Multiplying fractions is simpler.

For:$$\frac{a}{b} \times \frac{c}{d} \times \frac{e}{f}$$ba​×dc​×fe​

Multiply numerators:$$a \times c \times e$$a×c×e

Multiply denominators:$$b \times d \times f$$b×d×f

Then simplify.

---

How Fraction Simplification Works

After calculation, the result is reduced to its lowest terms.

A fraction is simplified by finding the Greatest Common Divisor (GCD) of the numerator and denominator.

For example:$$\frac{24}{36}$$3624​

GCD = 12

Divide both by 12:$$\frac{24}{36}=\frac{2}{3}$$3624​=32​

The calculator performs this automatically.

Example 1: Adding Three Fractions

Let's calculate:$$\frac{1}{2}+\frac{1}{4}+\frac{1}{8}$$21​+41​+81​

Common Denominator

8

Convert fractions:$$\frac{4}{8}+\frac{2}{8}+\frac{1}{8}$$84​+82​+81​

Add numerators:$$\frac{7}{8}$$87​

Result

Output	Value
Simplified Fraction	7/8
Decimal Value	0.875

---

Example 2: Subtracting Three Fractions

Calculate:$$\frac{5}{6}-\frac{1}{3}-\frac{1}{6}$$65​−31​−61​

Convert to common denominator:$$\frac{5}{6}-\frac{2}{6}-\frac{1}{6}$$65​−62​−61​

Subtract:$$\frac{2}{6}$$62​

Simplify:$$\frac{1}{3}$$31​

Result

Output	Value
Simplified Fraction	1/3
Decimal Value	0.333333

Example 3: Multiplying Three Fractions

Calculate:$$\frac{2}{3}\times\frac{3}{5}\times\frac{5}{8}$$32​×53​×85​

Multiply numerators:$$2\times3\times5=30$$2×3×5=30

Multiply denominators:$$3\times5\times8=120$$3×5×8=120

Result:$$\frac{30}{120}$$12030​

Simplify:$$\frac{1}{4}$$41​

Result

Output	Value
Simplified Fraction	1/4
Decimal Value	0.25

---

Fraction to Decimal Conversion

Many real-world applications use decimal values instead of fractions.

The calculator converts fractions into decimals using:$$Decimal = Numerator \div Denominator$$Decimal=Numerator÷Denominator

Example:$$\frac{3}{4}=0.75$$43​=0.75

This helps users compare values more easily.
