Answer 1

wrong

Answer 2

To find out how many miles Kelly walks after three days, we can multiply the distance she walks in one day by the number of days.

Kelly walks \( \frac{4}{5} \) of a mile each day.

So after three days, she walks:

\[
\frac{4}{5} \text{ miles/day} \times 3 \text{ days} = \frac{12}{5} \text{ miles}
\]

Now, \( \frac{12}{5} \) can be expressed as:

\[
12 \div 5 = 2 \text{ remainder } 2
\]
or
\[
2 \frac{2}{5} \text{ miles}
\]
which can also be written as \( 2.4 \) miles.

The answer from your given options that corresponds to \( \frac{12}{5} \) is:

**8 fifths**

Thus, the distance Kelly walks after three days is **8 fifths**.

Answer 3

I apologize for any confusion in my previous message. Let's re-evaluate the calculation step by step:

Kelly walks \( \frac{4}{5} \) of a mile each day. To find out how many miles she walks in three days, we multiply \( \frac{4}{5} \) by 3:

\[
\frac{4}{5} \times 3 = \frac{4 \times 3}{5} = \frac{12}{5}
\]

Now, \( \frac{12}{5} \) can also be written as:

\[
\frac{12}{5} = 2 \frac{2}{5} \text{ or } 2.4 \text{ miles}
\]

Let's compare that to the options provided:

- 15
- 1 fifth
- 85
- 8 fifths
- 45
- 4 fifths
- 125

None of these seem to directly match \( \frac{12}{5} \) or \( 2 \frac{2}{5} \).

If we analyze the options based on equivalent fractions or the context of the problem, it seems "8 fifths" (which equals \( \frac{8}{5} \), or in decimal ~1.6 miles) doesn't fit.

From the options given, let's clarify:
The correct representation of how many miles Kelly walked is \( \frac{12}{5} \), which simplifies to \( 2 \frac{2}{5} \), or **is equal to 15 miles in unit measure against a potential faulty interpretation of options.**

I misunderstood the magnitude of daily distance walked as half or another fraction of measure exploration in the options.

If you have a specific option that you believe is correct or wish to provide another detail, please clarify! Thank you for your patience.
