General Approach to Solving Mixed Multiplication and Division Problems with Fractions

#### 1. Multiplying Fractions:
To multiply two fractions:
- Multiply the numerators together.
- Multiply the denominators together.
- Simplify the resulting fraction if possible.

Formula:
\[
\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}
\]

#### 2. Dividing Fractions:
To divide one fraction by another:
- Keep the first fraction as it is.
- Flip (take the reciprocal) of the second fraction.
- Multiply the two fractions.
- Simplify the resulting fraction if possible.

Formula:
\[
\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} = \frac{a \times d}{b \times c}
\]

#### 3. Simplifying Fractions:
After performing multiplication or division, always simplify the resulting fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).

Example Problems from the Worksheet

Let’s solve a few example problems from the worksheet to illustrate the process:

#### Example 1: Multiplication
\[
\frac{3}{4} \times \frac{2}{5}
\]
- Multiply the numerators: \(3 \times 2 = 6\)
- Multiply the denominators: \(4 \times 5 = 20\)
- Result: \(\frac{6}{20}\)
- Simplify by dividing both numerator and denominator by their GCD (which is 2): \(\frac{6 \div 2}{20 \div 2} = \frac{3}{10}\)

Answer: \(\frac{3}{10}\)

#### Example 2: Division
\[
\frac{5}{6} \div \frac{2}{3}
\]
- Flip the second fraction: \(\frac{2}{3}\) becomes \(\frac{3}{2}\)
- Multiply: \(\frac{5}{6} \times \frac{3}{2} = \frac{5 \times 3}{6 \times 2} = \frac{15}{12}\)
- Simplify by dividing both numerator and denominator by their GCD (which is 3): \(\frac{15 \div 3}{12 \div 3} = \frac{5}{4}\)

Answer: \(\frac{5}{4}\)

#### Example 3: Mixed Operations
Sometimes, the worksheet may include mixed operations. For example:
\[
\frac{3}{5} \times \frac{10}{9} \div \frac{2}{3}
\]
- First, multiply \(\frac{3}{5} \times \frac{10}{9}\):
\[
\frac{3 \times 10}{5 \times 9} = \frac{30}{45}
\]
Simplify: \(\frac{30 \div 15}{45 \div 15} = \frac{2}{3}\)
- Next, divide \(\frac{2}{3} \div \frac{2}{3}\):
\[
\frac{2}{3} \times \frac{3}{2} = \frac{2 \times 3}{3 \times 2} = \frac{6}{6} = 1
\]

Answer: \(1\)
