Answer:
You would have walked a total of 7/10 miles or .7 miles.
Step-by-step explanation:
First you have to make the fractions have a common denominator. Let's do 10.
1/5 =2/10 you multiply the top and bottom by 2 to get a bottom of 10
1/2=5/10 you multiply the top and bottom by 5 to get a bottom of 10
Now we can add these,
2/10 + 5/10= 7/10 You do not add the denominators, only the numerators when the denominators are equal.
You would have walked a total of 7/10 miles or .7 miles.
