113 miles apart.

Explanation:

The trail is 713 miles long, and there are 6 markers on the trail.

In order to solve this, you have to divide 713 by 6. To do this, you must first change 713 into an improper fraction of 223. You find this by multiplying the whole number, 7, by the denominator, 3, and then adding the numerator, 1.

After you change the fraction, you take 223 and divide it by 6.

223÷6

To do this, you must first change 6 into a fraction. You can change any whole number into a fraction by putting it over 1, in this case, like this: 61.

When dividing fractions, you must always flip the second number, so the problem would be

223×16.

This gives you 2218 because you simply multiply across the top and across the bottom.

Now, you take it down to simplest form and get 1618 and then to 113.
