How to Simplify Fractions?

Understanding Fractions

A fraction represents a part of a whole and is composed of a numerator (top number) and a denominator (bottom number). Simplifying fractions involves reducing them to their simplest form, where the numerator and denominator share no common factors other than $1$.

Steps to Simplify Fractions

1. Find the Greatest Common Divisor (GCD):

• The GCD of two numbers is the largest number that divides both without leaving a remainder.

2. Divide the Numerator and Denominator by the GCD:

• This reduces the fraction to its simplest form.

Example 1: Simplify $\frac{4}{6}$

1. Find the GCD of $4$ and $6$ :

• Factors of $4: 1, 2, 4$
• Factors of $6: 1, 2,3,6$
• GCD: $2$

2. Divide numerator and denominator by $2$ :

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

3. Simplified Fraction: $\frac{2}{3}$

Therefore, $\frac{4}{6}$ simplified is $\frac{2}{3}$.

Example 2: Simplify $\frac{6}{8}$

1. Find the GCD of $6$ and $8$ :

• Factors of $6: 1, 2, 3, 6$
• Factors of $8: 1, 2, 4, 8$
• GCD: $2$

2. Divide numerator and denominator by $2$ :

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

3. Simplified Fraction: $\frac{3}{4}$

Therefore, $\frac{6}{8}$ simplified is $\frac{3}{4}$.

How to Simplify Radicals?

Understanding Radicals

A radical expression involves roots, such as square roots $(\sqrt{ })$, cube roots $(\sqrt[3]{ })$, and so on. Simplifying radicals involves expressing the radical in its simplest form.

Steps to Simplify Radical Expressions

1. Factor the Number Under the Radical:

• Break it down into its prime factors.

2. Identify Perfect Squares (or Cubes):

• Group the factors into pairs (for square roots).

3. Move Factors Outside the Radical:

• For each pair, take one factor out of the radical.

4. Multiply Factors Outside and Inside:

• Simplify the expression by multiplying.

Example: Simplify $\sqrt{50}$

1. Factor 50:

• $50=2 \times 5 \times 5$

2. Identify Pairs:

• Pair of 5 s .

3. Move Factor Outside:

• $\sqrt{50}=5 \sqrt{2}$

Therefore, $\sqrt{50}$ simplified is $5 \sqrt{2}$.

Simplifying Radical Expressions with Variables

Example: Simplify $\sqrt{32 x^4 y^5}$

1. Factor $32$:

• $32=2 \times 2 \times 2 \times 2 \times 2$

2. Identify Pairs:

• Pairs of $2 \mathrm{~s}:(2 \times 2),(2 \times 2)$, one $2$ remains.

3. Variables:

• $x^4$ becomes $x^2$ outside.
• $y^5$ becomes $y^2$ outside and $y$ inside.

4. Simplify:

• $\sqrt{32 x^4 y^5}=4 x^2 y^2 \sqrt{2 y}$

How to Simplify Algebraic Expressions?

Combining Like Terms

Like terms are terms that have the same variables raised to the same powers.

Steps:

1. Identify Like Terms:

• Terms with the same variables and exponents.

2. Combine Coefficients:

• Add or subtract the coefficients of like terms.

Example: Simplify $3 x+5 x-2 x$

• Combine coefficients: $(3+5-2) x=6 x$

Therefore, the simplified expression is $6 x$.

Using the Distributive Property

The distributive property allows you to eliminate parentheses by distributing multiplication over addition or subtraction.

Formula:

$$ a(b+c)=a b+a c $$

Example: Simplify $2(3 x+4)$

• Distribute 2: $2 \times 3 x+2 \times 4=6 x+8$

Therefore, the simplified expression is $6 x+8$.

Simplifying Complex Expressions

Example: Simplify $\frac{4 x^2-8 x}{4 x}$

1. Factor Numerator:

• $4 x(x-2)$

2. Simplify Fraction:

• $\frac{4 x(x-2)}{4 x}$

3. Cancel Common Factors:

• $x$ and 4 cancel out.

4. Result:

• $x-2$

Therefore, the simplified expression is $x-2$.

How to Simplify Complex Fractions?

Understanding Complex Fractions

A complex fraction has a fraction in the numerator, denominator, or both.

Steps to Simplify Complex Fractions

1. Find a Common Denominator:

• For all fractions involved.

2. Combine Numerator and Denominator:

• Simplify the fractions.

3. Simplify the Overall Fraction:

• Multiply numerator and denominator by the reciprocal if necessary.

Example: Simplify $\frac{\frac{1}{2}}{\frac{3}{4}}$

1. Find Reciprocal of Denominator:

• Reciprocal of $\frac{3}{4}$ is $\frac{4}{3}$

2. Multiply Numerator by Reciprocal:

• $\frac{1}{2} \times \frac{4}{3}=\frac{4}{6}$

3. Simplify Result:

• $\frac{4}{6}=\frac{2}{3}$

Therefore, the simplified fraction is $\frac{2}{3}$.

Example: Simplify $\sqrt[3]{x^6}$

• Convert to exponent: $x^{\frac{6}{3}}=x^2$

Therefore, $\sqrt[3]{x^6}=x^2$.

How to Simplify Expressions with Multiple Variables?

Applying the Same Principles

• Combine Like Terms: Only terms with the same variables and exponents.
• Factor and Simplify: Factor expressions when possible to simplify.

Example: Simplify $2 x y+3 x^2 y-x y$

1. Identify Like Terms:

• $2 x y$ and $-x y$

2. Combine Like Terms:

• $(2 x y-x y)+3 x^2 y=x y+3 x^2 y$

Therefore, the simplified expression is $x y+3 x^2 y$.

Conclusion

Simplifying expressions is a foundational skill in mathematics that enhances problem-solving abilities and paves the way for understanding more complex concepts. Whether you're simplifying fractions, radicals, or algebraic expressions, the principles remain consistent: break down the expression into its simplest components and rebuild it in a more concise form.
