🔢 Step 1: Understanding the Basics of Fractions

A fraction represents a part of a whole. It’s made up of two key parts:

• Numerator (Top Number): The number of parts you have.
• Denominator (Bottom Number): The total number of equal parts that make up the whole.

Interactive Example:

Imagine a pizza 🍕 cut into 4 equal slices. If you have 1 slice, what fraction of the pizza do you have?

$$\frac{1}{4}$$

• Numerator = 1 (the number of slices you have),
• Denominator = 4 (the total number of slices).

So, 1 slice out of 4 is represented as $\frac{1}{4}$!

⚖️ Step 2: Simplifying Fractions

We can simplify fractions to make them easier to work with. To simplify, divide both the numerator and the denominator by their Greatest Common Divisor (GCD).

Example:

Let’s simplify $\frac{6}{8}$.

1. Find the GCD of 6 and 8, which is 2.
2. Divide both the numerator and denominator by 2:

$$\frac{6 \div 2}{8 \div 2} = \frac{3}{4}$$

Simplified Fraction: $\frac{3}{4}$!

Try it Yourself:

Simplify $\frac{12}{16}$. What do you get?
Hint: The GCD of 12 and 16 is 4.

🔄 Step 3: Converting Between Improper Fractions and Mixed Numbers

Improper Fractions have a numerator that’s larger than the denominator. Mixed Numbers are a combination of a whole number and a fraction.

Example 1: Improper Fraction to Mixed Number

Convert $\frac{7}{4}$ into a mixed number.

1. Divide 7 by 4: 7 ÷ 4 = 1 with a remainder of 3.
2. The whole number is 1, and the remainder forms the fraction: $\frac{3}{4}$.

So, $\frac{7}{4}$ becomes $1 \frac{3}{4}$.

Example 2: Mixed Number to Improper Fraction

Convert $2 \frac{1}{2}$ into an improper fraction.

1. Multiply the whole number (2) by the denominator (2): 2 × 2 = 4.
2. Add the numerator of the fraction (1): 4 + 1 = 5.

So, $2 \frac{1}{2}$ becomes $\frac{5}{2}$.

Try it Yourself:

Convert $\frac{9}{5}$ into a mixed number!

➕ Step 4: Adding and Subtracting Fractions

To add or subtract fractions, the denominators must be the same. If they’re different, find the Least Common Denominator (LCD) first.

Example 1: Same Denominator

Add $\frac{3}{8}$ and $\frac{2}{8}$.

Since the denominators are the same, simply add the numerators:

$$\frac{3}{8} + \frac{2}{8} = \frac{5}{8}$$

Example 2: Different Denominators

Add $\frac{1}{4}$ and $\frac{1}{6}$.

1. The LCD of 4 and 6 is 12.
2. Convert each fraction to have a denominator of 12:
   • $\frac{1}{4} = \frac{3}{12}$
   • $\frac{1}{6} = \frac{2}{12}$
3. Add the fractions:

$$\frac{3}{12} + \frac{2}{12} = \frac{5}{12}$$

Try it Yourself:

Add $\frac{5}{12}$ and $\frac{1}{4}$. What’s the result?

---

✖️ Step 5: Multiplying Fractions

To multiply fractions, simply multiply the numerators and denominators.

Example:

Multiply $\frac{2}{3}$ by $\frac{4}{5}$.

$$\frac{2}{3} \times \frac{4}{5} = \frac{2 \times 4}{3 \times 5} = \frac{8}{15}$$

Try it Yourself:

Multiply $\frac{5}{8}$ by $\frac{7}{9}$. What’s the result?

---

➗ Step 6: Dividing Fractions

To divide fractions, multiply by the reciprocal (flip the second fraction).

Example:

Divide $\frac{3}{4}$ by $\frac{2}{5}$.

1. Reciprocal of $\frac{2}{5}$ is $\frac{5}{2}$.
2. Multiply $\frac{3}{4}$ by $\frac{5}{2}$:

$$\frac{3}{4} \times \frac{5}{2} = \frac{3 \times 5}{4 \times 2} = \frac{15}{8}$$

Try it Yourself:

Divide $\frac{5}{6}$ by $\frac{2}{3}$. What do you get?

---

🔢 Step 7: Converting Fractions to Decimals

To convert a fraction to a decimal, simply divide the numerator by the denominator.

Example:

Convert $\frac{3}{4}$ into a decimal.

$$3 \div 4 = 0.75$$

So, $\frac{3}{4} = 0.75$.

Try it Yourself:

Convert $\frac{5}{8}$ into a decimal.

1. Simplify $\frac{12}{16}$.
2. Convert $\frac{9}{4}$ to a mixed number.
3. Add $\frac{2}{5}$ and $\frac{3}{10}$.
4. Multiply $\frac{5}{8}$ by $\frac{7}{9}$.
5. Divide $\frac{5}{6}$ by $\frac{2}{3}$.
