Multiply 1/9 by 4 1/5. Write the answer in simplest form.

To multiply the fractions, first convert the mixed number to an improper fraction.

4 1/5 = (4 * 5 + 1)/5 = 21/5

Now, multiply the improper fraction by 1/9:

(1/9) * (21/5) = (1 * 21) / (9 * 5)
= 21/45

To simplify the fraction, find the greatest common divisor (GCD) of the numerator and denominator, which is 3. Divide both the numerator and denominator by 3.

21/45 = (21/3) / (45/3) = 7/15

So, the answer in simplest form is 7/15.
