Understanding Fractions

Before using the calculator, it's important to understand the components of a fraction.

A fraction consists of:

Numerator

• The number above the fraction line.

Denominator

• The number below the fraction line.

Example:$$\frac{3}{4}$$43​

• Numerator = 3
• Denominator = 4

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

Fraction Addition Formula

To add fractions, they must have a common denominator.

Formula

$$\frac{a}{b}+\frac{c}{d}+\frac{e}{f}$$ba​+dc​+fe​

The fractions are converted to equivalent fractions with a common denominator before adding the numerators.

---

Addition Example

Calculate:$$\frac{1}{2}+\frac{1}{3}+\frac{1}{6}$$21​+31​+61​

Common denominator = 6$$\frac{3}{6}+\frac{2}{6}+\frac{1}{6}$$63​+62​+61​

Add numerators:$$\frac{6}{6}$$66​

Result:$$1$$1

Decimal:

1.000

Mixed Number:

1

---

Fraction Subtraction Formula

Subtraction follows the same common denominator principle.

Formula

$$\frac{a}{b}-\frac{c}{d}-\frac{e}{f}$$ba​−dc​−fe​

---

Subtraction Example

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​

Decimal:

0.333333

---

Fraction Multiplication Formula

Multiplication is usually simpler than addition or subtraction.

Formula

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

Multiply numerators together.

Multiply denominators together.

---

Multiplication Example

$$\frac{2}{3}\times\frac{3}{4}\times\frac{5}{6}$$32​×43​×65​

Numerators:$$2\times3\times5=30$$2×3×5=30

Denominators:$$3\times4\times6=72$$3×4×6=72

Result:$$\frac{30}{72}$$7230​

Simplified:$$\frac{5}{12}$$125​

Decimal:

0.416667

---

Fraction Division Formula

Division involves multiplying by reciprocals.

Formula

$$\frac{a}{b}\div\frac{c}{d}\div\frac{e}{f}$$ba​÷dc​÷fe​

Convert divisors into reciprocals and multiply.

---

Division Example

$$\frac{3}{4}\div\frac{1}{2}\div\frac{3}{5}$$43​÷21​÷53​

Step 1:$$\frac{3}{4}\times\frac{2}{1}\times\frac{5}{3}$$43​×12​×35​

Step 2:$$\frac{30}{12}$$1230​

Simplified:$$\frac{5}{2}$$25​

Mixed Number:$$2\frac{1}{2}$$221​

Decimal:

2.5

---

What Is Fraction Simplification?

Fraction simplification means reducing a fraction to its lowest terms.

Example:$$\frac{12}{18}$$1812​

Greatest Common Divisor (GCD):

6

Divide both numbers by 6:$$\frac{2}{3}$$32​

The calculator automatically performs this step.

Understanding Decimal Results

Many people prefer decimal numbers for practical applications.

Examples:

Fraction	Decimal
1/2	0.5
1/4	0.25
3/4	0.75
2/3	0.666667
