In the school walkathon, Bev walked 2 1/5 miles, Dennis walked 3 2/10 miles, and Natalie walked 2 3/5 miles. what was the total distance they walked. write your answer as a whole number and as an improper fraction.
2 1/5 = 2 2/10
2 3/5 = 2 6/10
2 2/10 + 3 2/10 + 2 6/10 = 7 10/10 = 8 = 80/10

To find the total distance the three students walked, we need to add up the distances walked by Bev, Dennis, and Natalie.
First, let's convert the mixed numbers to improper fractions:
Bev: 2 1/5 = 11/5
Dennis: 3 2/10 = 32/10
Natalie: 2 3/5 = 13/5
Now, we can add the three fractions together:
11/5 + 32/10 + 13/5
To add fractions, we need to have a common denominator. In this case, the common denominator for 5 and 10 is 10.
So, let's rewrite the three fractions with a common denominator of 10:
11/5 + 32/10 + 13/5
= 22/10 + 32/10 + 26/10
Now we can add the numerators together:
= (22 + 32 + 26) / 10
= 80/10
Finally, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 10:
80/10 = 8/1
Therefore, the total distance the three students walked is 8 miles, or 8 1/10 as an improper fraction.
