Answer:To find out how many miles Anna walked, we need to determine the distance covered by 5/8 of the trail.
First, let's set up a proportion. We know that Anna walked 5/8 of the trail, which is equivalent to 9 miles. We can set up the proportion as follows:
(5/8) / x = 9 / 1
To solve for x, the distance Anna walked, we can cross-multiply:
5 * 1 = 8 * 9
5 = 72
Since 5 does not equal 72, this means there is an error in the proportion. Let's correct it.
The correct proportion should be:
x / (5/8) = 9 / 1
To solve for x, we can multiply both sides of the equation by (5/8):
x = (9 / 1) * (5 / 8)
x = 45 / 8
Now, let's simplify the fraction:
x = 5.625
Therefore, Anna walked approximately 5.625 miles.
