Understanding Fractions
Before learning multiplication, it helps to understand the basic components of a fraction.
A fraction consists of:
Numerator
- Top number
- Represents parts being considered
Denominator
- Bottom number
- Represents total equal parts
Example:
3/4
Where:
- 3 = Numerator
- 4 = Denominator
Formula for Multiplying Three Fractions
The multiplication process is straightforward.
Suppose you have:
a/b × c/d × e/f
The multiplication formula is:b×d×fa×c×e
Simply:
- Multiply all numerators together.
- Multiply all denominators together.
The result may then be simplified.
Simplifying Fractions
After multiplication, the resulting fraction may not be in its simplest form.
To simplify:
- Find the Greatest Common Divisor (GCD).
- Divide numerator and denominator by the GCD.
Example:
12/18
GCD = 6
Simplified result:
2/3
Example 1: Basic Fraction Multiplication

15/48
Simplify
Divide by 3:
5/16
Decimal Value
5 ÷ 16 = 0.3125
Final Answer:
- Unsimplified: 15/48
- Simplified: 5/16
- Decimal: 0.3125
Example 2: Larger Fractions
Multiply:
4/5 × 6/7 × 3/8
Numerators
4 × 6 × 3 = 72
Denominators
5 × 7 × 8 = 280
Result:
72/280
Simplify
Divide by 8:
9/35
Decimal Value
9 ÷ 35 = 0.257143
Final Result:
- Unsimplified: 72/280
- Simplified: 9/35
- Decimal: 0.257143
Example 3: Improper Fraction Result
Multiply:
5/2 × 3/4 × 7/3

105/24
Simplify
35/8
Mixed Number
35 ÷ 8 = 4 remainder 3
Mixed Number:
4 3/8
Final Answer:
- Unsimplified: 105/24
