Final answer:
To multiply the fractions 4/5 by 1/5, you multiply the numerators to get 4, and the denominators to get 25, resulting in the fraction 4/25.
Step-by-step explanation:
When multiplying fractions, as the question asks us to do, you multiply the numerators (top numbers) together and the denominators (bottom numbers) together. In this problem, we have 4/5 times 1/5. To multiply, we take 4 times 1 for the numerator and 5 times 5 for the denominator, getting us 4/25.
The process would look like this:
- Multiply the numerators: 4 x 1 = 4
- Multiply the denominators: 5 x 5 = 25
- Combine the results: 4/25
So, the answer to 4/5 multiplied by 1/5 is 4/25, which is option a.
