Len walks 3/10 mile in the morning. He walks 2/5 mile in the afternoon to a friends house. Len says that he walks a total of 5/15 mile in the morning and afternoon which two satements are true

A. since 3/10 + 2/5 is 5/15, the total of 5/15 is reasonable

B. since 5/15 is less than 2/5, the total of 5/15 is not reasonable

C. the fractions 5/15,3/10, and 2/5 are all less than 1/2, so the total of 5/15 is reasonable

D. the fractions 5/15 is 1/3, and 1/3 is greater than 3/10. Since 5/15 is greater than one of the addends, the total of 5/15 is reasonable

E. the fractions 3/10 and 2/5 are each greater than 1/4, so the total of 5/15 is not reasonable.

Answer:The answer is not reasonable.

Step-by-step explanation:Ok so lets start by finding the Common Denominator, which we'll say is 10 so 3/10 then we can say that 2/5 and 4/10 is the same thing, 7/10 of a mile was walked, 7/10 and 5/15 are not the same.
