# Jill walked #8 1/8# miles to a park and then #7 2/5# miles home. How many miles did she walk in all?

Okay, I think the easiest way to approach this problem is to first convert the mixed fractions to irregular fractions:

We want the total number of miles, so our equation is:

The LCD of 5 and 8 is 5*8=40, so:

Hope this helps!

We can do this a couple of ways.

Improper fractions

Now we need to have the denominators be the same:

And now we divide it back out:

We can avoid the large numbers by adding the whole numbers first, then adding the fractions:

And now we add the fractions by finding a common denominator:

To find out how many miles Jill walked in total, you simply add the distance she walked to the park and the distance she walked back home.

Distance walked to the park = 8 1/8 miles Distance walked home = 7 2/5 miles

To add these distances, you can convert the mixed numbers to improper fractions:

8 1/8 miles = 8 + 1/8 = 8 + 1/8 = 8 + 1/8 = 65/8 miles 7 2/5 miles = 7 + 2/5 = 7 + 2/5 = 7 + 2/5 = 37/5 miles

Now, add the distances:

65/8 miles + 37/5 miles = (65 * 5)/(8 * 5) + (37 * 8)/(5 * 8) = 325/40 + 296/40 = (325 + 296)/40 = 621/40 miles

So, Jill walked a total of 621/40 miles.
