1 × 1 = 1
\text{Numerator: } 1 \times 1 = 1
Step 3
Multiply the Denominators
Multiply all the bottom numbers (denominators) together:
4 × 5 = 20
\text{Denominator: } 4 \times 5 = 20
Step 4
Write the Unsimplified Result
Putting the products together:
\frac{1}{4} \times \frac{1}{5} = \frac{1}{20}
Step 5
Check for Simplification
The GCF of 1 and 20 is 1, so the fraction is already in simplest form.
\frac{1}{20} \text{ (already simplified)}
Step 6
Final Answer
The result is 1/20
