Step 1:
: Recall that the product of two fractions can be found by multiplying the numerators and multiplying the denominators separately.

\frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd}
This gives us the formula:

Step 2:
: In this case, we have a = \frac{1}{3} and b = \frac{4}{5}.

ac = \frac{1}{3} \times \frac{4}{5} = \frac{4}{15}
Multiply the numerators:

Step 3:
: Multiply the denominators:

bd = \frac{3}{1} \times \frac{5}{4} = \frac{15}{4}

Step 4:
: Combine the results from Steps 2 and 3 using the formula from Step 1:

\frac{1}{3} \times \frac{4}{5} = \frac{4}{15} \times \frac{15}{4} = \frac{60}{60}

Step 5:
: Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 60 in this case:

\frac{60}{60} = \frac{60 \div 60}{60 \div 60} = \frac{1}{1}

Final Answer

The product of \frac{1}{3} and \frac{4}{5} is equal to 1.
