What is a Fraction?
A fraction is a way to show parts of a whole. It has two numbers: the top number, called the numerator, and the bottom number, called the denominator. The numerator tells how many parts you have, while the denominator shows how many equal parts the whole is divided into.
For example, in the fraction $\frac{3}{4}$, the numerator (3) means you have three parts, and the denominator (4) means the whole is split into four equal pieces. So, $\frac{3}{4}$ represents “three out of four parts.”
In a fraction, there are three key components:
- Numerator – The top number in a fraction. It represents how many parts of a whole are taken.
- Denominator – The bottom number in a fraction. It represents the total number of equal parts the whole is divided into.
- Whole Number – In a mixed fraction, the whole number is the integer part that stands separately from the fraction.
Types of Fractions:
1. Proper Fractions – The numerator is smaller than the denominator.
- Example: $\frac{3}{4}$ → (3 is the numerator, 4 is the denominator).
- Condition: Numerator < Denominator
- Meaning: Represents a value less than 1.
2. Improper Fractions – The numerator is greater than or equal to the denominator.
- Example: $\frac{5}{3}$ → (5 is the numerator, 3 is the denominator).
- Condition: Numerator ≥ Denominator.
- Meaning: Represents a value greater than or equal to 1.
3. Mixed Fractions – A combination of a whole number and a proper fraction.
- Example: 2$\frac{1}{3}$ → (2 is the whole number, 1 is the numerator, and 3 is the denominator).
- Meaning: Represents a value greater than 1 but written in a form that separates the whole part from the fraction.
Fractions are part of everyday life—you see them when splitting food, measuring ingredients, or dividing time. You can also convert fractions to decimals to make calculations or comparisons easier.
Why Can’t the Numerator or Denominator Be Zero?
When working with fractions, it is important to understand the restrictions on numerators and denominators:
- Numerator must be nonzero (except for zero fractions): A fraction with a zero numerator (e.g., $\frac{0}{4}$) always results in zero, regardless of the denominator. While such fractions are valid, they are often unnecessary in calculations.
- Denominator cannot be zero: A fraction with a denominator of zero (e.g., $\frac{3}{0}$) is undefined in mathematics because division by zero is impossible. Since division is the process of splitting into equal parts, having zero parts to divide by makes no logical sense.
In short, while a numerator of zero makes the entire fraction zero, a denominator of zero makes the fraction undefined, which is why it is not allowed.
How to Manually Convert Mixed Numbers to Improper Fractions
To manually convert a mixed number into an improper fraction, follow these simple steps:
Step 1: Multiply the Whole Number by the Denominator
Take the whole number part and multiply it by the denominator of the fractional part.
Step 2: Add the Numerator
Add the result from Step 1 to the original numerator. This sum becomes the new numerator.
Step 3: Write the Improper Fraction
Keep the denominator the same. Write the new numerator over the original denominator.
Formula for Mixed Numbers to Improper Fractions:
$ \text{Whole Number} \ \frac{\text{Numerator}}{\text{Denominator}} = \frac{(\text{Whole Number} \times \text{Denominator}) + \text{Numerator}}{\text{Denominator}} $
Example for Mixed Numbers to Improper Fractions:
✦ Example 1
Convert: $3\frac{2}{5}$
Step 1: Multiply the whole number by the denominator:
$3 \times 5 = 15$
Step 2: Add the numerator:
$15 + 2 = 17$
Final Answer:
$3\frac{2}{5} = \frac{17}{5}$
✦ Example 2
Convert: $6\frac{1}{4}$
Step 1: $6 \times 4 = 24$
Step 2: $24 + 1 = 25$
Final Answer:
$6\frac{1}{4} = \frac{25}{4}$
✦ Example 3
Convert: $4\frac{3}{8}$
Step 1: $4 \times 8 = 32$
Step 2: $32 + 3 = 35$
Final Answer:
$4\frac{3}{8} = \frac{35}{8}$
✦ Example 4
Convert: $2\frac{5}{6}$
Step 1: $2 \times 6 = 12$
Step 2: $12 + 5 = 17$
Final Answer:
$2\frac{5}{6} = \frac{17}{6}$
✦ Example 5
Convert: $5\frac{7}{9}$
Step 1: $5 \times 9 = 45$
Step 2: $45 + 7 = 52$
Final Answer:
$5\frac{7}{9} = \frac{52}{9}$
Formulas for Simplifying Fractions
1. Mixed to Improper Fraction Formula
Improper Fraction = $\frac{(\text{Whole Number} \times \text{Denominator}) + \text{Numerator}}{\text{Denominator}} $
2. Simplifying Fractions Formula
$ \frac{a}{b} = \frac{a \div \gcd(a, b)}{b \div \gcd(a, b)} $
Where GCD = Greatest Common Divisor of numerator and denominator.
3. Improper Fraction to Mixed Number Formula
$ \text{Mixed Number} = \text{Quotient} \ \frac{\text{Remainder}}{\text{Denominator}} $
Where:
- Quotient = Integer part of division
- Remainder = What’s left over
Example 1: Mixed to Simplest Mixed
Input: $2\frac{4}{6}$
Step 1: Convert to improper:
$ (2 \times 6) + 4 = 12 + 4 = 16 \Rightarrow \frac{16}{6} $
Step 2: Simplify:
$ \gcd(16,6) = 2, \quad \frac{16}{6} = \frac{8}{3} $
Step 3: Convert to mixed:
$ 8 \div 3 = 2 \text{ R } 2 \Rightarrow 2\frac{2}{3} $
Example 2: Mixed to Simplest Mixed
Input: $3\frac{9}{12}$
Convert to improper:
$ (3 \times 12) + 9 = 36 + 9 = 45 \Rightarrow \frac{45}{12} $
Simplify:
$ \gcd(45,12) = 3, \quad \frac{45}{12} = \frac{15}{4} = 3\frac{3}{4} $
Example 3: Improper to Simplest Mixed
Input: $\frac{36}{8}$
Simplify:
$ \gcd(36,8) = 4, \quad \frac{36}{8} = \frac{9}{2} $
Convert to mixed:
$ 9 \div 2 = 4 \text{ R } 1 \Rightarrow 4\frac{1}{2} $
Example 4: Proper Fraction to Simplest
Input: $\frac{18}{24}$
Simplify:
$ \gcd(18,24) = 6$,
$\quad \frac{18}{24}$ = $\frac{3}{4} $
Example 5: Mixed with Larger Numbers
Input: $5\frac{15}{20}$
Convert to improper:
$ (5 \times 20) + 15$ = 100 + 15 = $\frac{115}{20} $
Simplify:
$ \gcd(115,20) = 5$
$\frac{115}{20}$ = $\frac{23}{4}$ = $5\frac{3}{4} $
